New Hampshire Spiders: Pomoć za slike i identifikaciju

Hladna, sjeverna klima znači da tradicionalna sezona pauka New Hampshirea traje od kasnog proljeća do rane jeseni.

Ljubitelji pauka gotovo uvijek moraju čekati do sredine ljeta kako bi istražili raznolikost pauka u Bijelim planinama.

Niže ležeći gradovi i veća stambena područja poput Manchestera i Nashua dijele iste vrste pauka. Zapravo, cijela Nova Engleska pruža prikladno stanište za pauke New Hampshirea. Dvije su najčešće vrste pauka u pogledu broja vrsta patuljci/paukovi i pauci skakači. Patuljci i Sheetweb pauci grade neuredne mreže oko grmlja, a veličina, većinom oko 1/16 inča, znači da su mreže vidljivije od pauka.

S druge strane, mnogi pauci skakači često narastu oko jedne četvrtine inča i stalno se pojavljuju po dvorištu. Video prikazuje brončanog pauka koji skače.

Što se tiče identifikacije pauka u New Hampshireu, najveći interes dolaze od pojedinaca koji vide pauke u svojim domovima i stanovima i žele znati je li pauk opasan.

Jednostavan odgovor je ne. Pauci su klasificirani kao korisni jer love štetočine insekata. Jedan vrlo uobičajen kopneni pauk, Eastern Parson ’s Spider, na gornjoj slici, odgovara tom opisu.

Mali popis prikazanih slika pauka obuhvaća reprezentativan uzorak državnih kućnih pauka i paukova travnjaka i vrta. Gumb pauka vodi do članaka koji pružaju dodatne slike i informacije o pauku. Cijeli vodič za pauke obuhvaća preko stotinu različitih vrsta pauka.

Identificiranje pauka paučine moglo bi biti zadatak za cijeli život. Dok mala skupina koja svoju mrežu gradi u stambenim područjima skreće najveću pozornost, zapravo je u Sjedinjenim Državama dokumentirano blizu četiri stotine vrsta.

Brojke ukazuju na to da je više od devedeset pet posto svih paukova paukova vanjskih pauka na koje nitko drugi ne misli osim na ekstremne ljubitelje pauka.

Dvije fizičke značajke, prisutnost okruglih trbuha s prvim nizom nogu duljim od ostalih, služe kao početni alati za identifikaciju. Boja tijela i uzorci trbuha služe kao sljedeći tragovi identifikacije.

Enoplognatha ovata, slika na vrhu stranice dobar je primjer. Prilično je česta duž sjevernog dijela Sjedinjenih Država. Međutim, mogu poprimiti nekoliko različitih boja i uzoraka trbuha.

Nema sumnje da je sjeverni pauk Crne udovice najpoznatiji pauk paučine New Hampshire. Samo su ženke klasificirane kao pauci od medicinske važnosti.

Identifikacija Crne udovice prilično je jednostavna. Mužjaci i ženke imaju crna tijela. Mužjaci i mladež obje vrste imaju bijele oznake na trbuhu. Osim toga, ženke su dvostruko veće od mužjaka s duljinom tijela obično oko pola centimetra.

Prisutnost crvene pješčane oznake na dnu trbuha predstavlja klasičnu identifikaciju polja. Oznake pješčanog sata sjeverne Crne udovice razbijene su u sredini.

Konačno, još jedan skup običnih kućnih pauka također pripada kategoriji paukova paučine. Većina pauka paučine ne dobiva uobičajena imena. Obični kućni pauk (Parasteatoda-tepidariorum i trokutasti kućni pauk iznimke su od pravila.

Nekoliko dodatnih vrsta Stedota nosi naziv False Widow pauci i često lutaju u zatvorenom prostoru. Dok njihova tijela imaju tamne boje, nedostaje im uzorak pješčanog sata. Steatoda americana je uobičajena vrsta pauka u New Hampshireu.

New Hampshire ugošćuje lijepu raznolikost pauka koji tkaju kugle iz roda Araneus. Šarena tijela i različiti trbušni uzorci, poput Mramornog tkanja, olakšavaju identifikaciju.

Ne zaboravite pauka ambara koji je proslavio Charlotte ’s Web, Araneus cavaticus. Obično nalikuju pjegavom orbaveru. Pogled ispod trbuha pomaže razjasniti identifikaciju. Pauci staje imaju više oznake zavoja na donjoj strani trbuha, a ne izrazita mjesta.


Obični kućni pauci



Florida sigurno ima velike kućne pauke. Osim pauka Huntsmana, na popis dodajte pauka Southern House. Njihova su tijela duga više od pola centimetra, a noge im povećavaju duljinu.

Formalno pripadaju tkačima pukotina i grade mreže u pukotinama oko kuće. Opet, ne smatraju se opasnima, samo su velike i zastrašujuće za pojedince koji nisu ljubitelji pauka.

Prvi stupac u galeriji također obuhvaća češće kućne pauke. Zanimljivo je napomenuti da se mnogi uobičajeni kućni pauci, poput podrumskih paukova i paukova, uklapaju u web kategoriju.

Dodajte uobičajene lovačke pauke kao što su paukovi na kopnu i pauci skakači, a to se prevodi i u mrežne paukove i u lovačke pauke koji svakodnevno dijele prostor s ljudima.

Pauci paučine također se uklapaju u kategoriju uobičajenih kućnih pauka. Kućni pauk trokutasti i obični kućni pauk (Parasteatoda-tepidariorum) predstavljaju dvije vrste paukova paučine koje se svrstavaju u dva najčešća kućna pauka od obale do obale.

Nekoliko dodatnih vrsta Stedota nosi naziv False Widow pauci i često lutaju u zatvorenom prostoru.

To ostavlja udovicama paucima iz roda Latrodectus da raspravljaju. Najčešći su od svih otrovnih pauka. Četiri vrste žive tijekom cijele godine na Floridi.

Dok obično grade gnijezda nisko do tla u četki i gomilama dna, na dnu roštilja ili stolica za travnjak. Povremeno se može naći u zatvorenom prostoru, posebno u šupama u dvorištu.

Naučiti više o tome kako prepoznati različite vrste paukova paukova u kući može biti jednako jednostavno ako na pametni telefon postavite mali, jeftini makro objektiv i usporedite slike.

Pauci trave također poznati kao tkači lijevka često lutaju kućom. Većina vrsta također izgleda vrlo slično s tankim, prugastim smeđim tijelima. Dugi prednji dijelovi na kraju trbuha pomažu im razlikovati se od vukova pauka.

Rakovi pauci obično ne ulaze u zatvorene prostore. Umjesto toga, oni teže cvijeću oko kuće. T Na slici su dvije vrste s bijelim tijelima i crvenim prugama. Tri roda takozvanih pauka cvjetnih rakova dolaze u različitim bojama, uključujući i žutu. Uzorci očiju i dlake na tijelu pravi su način za njihovo prepoznavanje.

Pet vrsta rasadnika i riblji pauk također se mogu naći u blizini stambenih područja, iako rjeđe od ostalih vrsta pauka. Općenito imaju tijela srednje veličine s nejasnim bojama koje im pomažu da se uklope u svoje okruženje.

Neuvježbanom oku mogu izgledati poput pauka vuka ili pauka trave.

Identifikacija pauka: tkači kugli

Prisutnost šarenih tijela s prepoznatljivim uzorcima čini pauke Floride u kategoriji tkalaca kugli među paukovima koje je najlakše identificirati.

Na primjer, zlatni svileni orbweavers imaju tanka smeđa pjegava tijela. Prisutnost najveće mreže u obliku kugle u Sjedinjenim Državama otežava njihovo propuštanje gdje god živjeli.

Vrste iz tri roda, Araneus, Neoscona i Argiope vjerojatno su najčešći tkači kugli u dvorištu.

Turiste sa Zapadne obale moglo bi zanimati činjenica da ondje živi nekolicina manje uobičajenih vrsta Araneus poput Araneus Cingulatus Araneus bicentenarius Araneus alboventris Araneus alboventris.

Crni i žuti vrtni pauci vjerojatno su najčešći argiopski pauci. Florida također ima svoju zasebnu verziju srebrne argiope (Argiope florida).

  • Klasifikacija Rod Nefila Obitelj Nephilidae Red Araneae Klasa Arachnida Phylum Arthropoda Kraljevstvo Životinje
  • Raspon veličina 2 cm - 4 cm (ženski), 5 mm (muški)

Pauci za tkanje zlatnih kugli grade velike, snažne mreže kuglica sa zlatnim sjajem.

Identifikacija

Pauci za tkanje zlatnih kugli veliki su pauci sa srebrnosivim do šljivovim tijelima i smeđecrnim, često žutim trakama. Mužjaci su sitni i crveno-smeđe do smeđe boje. Glavna razlika između uobičajenih vrsta Sydneya, Nephila plumipes i N. edulis (što je češće u kopnenim regijama) prisutnost je 'knota ' na prednjoj strani prsne kosti (ploča u obliku srca na donjoj strani tijela između nogu) N. plumipes.

Stanište

Pauci koji tkaju zlatne kugle nalaze se u suhim otvorenim šumama i šumama, obalnim grmovima pješčanih dina i staništima mangrova.

Svi pauci koji tkaju kugle čine ovješene, ljepljive, kuglaste mreže u obliku kotača. Mreže se postavljaju u otvore između drveća i grmlja gdje će insekti vjerojatno letjeti.

Distribucija

Pauci koji tkaju zlatne kugle nalaze se u suhim otvorenim šumama i šumama, obalnim grmovima pješčanim dinama i staništima mangrova, s Nephila edulis i N. plumipes dvije vrste koje se nalaze u regiji Sydney.

U Sydneyu, grmlje i drveće Kraljevskog botaničkog vrta dobro su mjesto za vidjeti ih, kao i šume mangrova u Bicentennial Parku i gradskom zaljevu Homebush Bay.

Hranjenje i dijeta

Predmeti plijena pauka koji pletu zlatne kugle su muhe, kornjaši, skakavci, drveni moljci i cikade. Ponekad njihove jake mreže uspijevaju zarobiti male ptice ili šišmiše, a pauk će ih omotati i hraniti se njima.

Druga ponašanja i prilagodbe

Pauci za tkanje zlatnih kugli grade velike, polutrajne mreže kuglica. Jaka svila ima zlatni sjaj. Ovi pauci ostaju u svojim mrežama dan i noć i stječu određenu zaštitu od napada ptica prisutnošću 'pregradne mreže ' niti na jednoj ili obje strane mreže kugle.

Poput križnog pauka St Andrew, vibrirat će svojom mrežom kako bi odvratili pozornost potencijalnim grabežljivcima. Ponekad se nađu agregati tkalaca Zlatnih kugli sa zamršenom mrežom preklapajućih mreža. Njihove mreže često su domaćini malim kleptoparazitskim paucima iz roda Argyrodes (često Quicksilver Spider, Argyrodes antipodeanus) koji nastanjuju veću paukovu mrežu i jedu manje insekte koji ostanu zarobljeni na mreži, čime pomažu da se mreža očisti od ostataka.

Ciklus životne povijesti

U skupini pauka koji tkaju zlatnu kuglu uobičajeno je da brojni sitni (6 mm) mužjaci žive oko rubova ženke i čekaju priliku za parenje. Nakon parenja, ženka pauka koja plete zlatnu kuglu omota svoju vrećicu s jajima u masu zlatne svile, koja se zatim skriva na lišću dalje od mreže, prerušena u uvijeni list ili grančicu grančica.

Predatori

Predatori tkalaca kugli uključuju nekoliko vrsta ptica i osa iz obitelji Sphecidae. Ose slijeću na mrežu, mame pauka na obod oponašajući vibracije insekata koji se bore, a zatim odnose pauka da se paralizira i pohrani kao živa hrana za mlade.

Opasnost po ljude

Tkalice kugle nerado grizu. Simptomi su obično zanemarivi ili blagi lokalni bolovi, ukočenost i oteklina. Povremeno se nakon ugriza mogu pojaviti mučnina i vrtoglavica.


Ponovno puštanje prirode

Prvo stvorenje koje mi je zapelo za oko prvog dana 2019 i natjerao me da uzmem fotoaparat, je li ovaj vrtni kuglični pauk. Njegova složena okrugla mreža nanizana je na okomite šiljke obične žurbe (Juncus effusus) pored našeg vrtnog jezerca.

Pauci vrtne kugle (Argiope) javljaju se diljem svijeta, uključujući Ameriku, Europu, Aziju, Australiju i Afriku. Mnogo je vrsta u ovom rodu, a ja nisam uspio točno odrediti o kojoj je vrsti riječ o ovom vrlo lijepom vrtnom sferu pauku.

Ova ženka pauka koja plete vrtne kugle ima šarene boje na nogama koje nose nježne osjetne dlačice. Trbuh je lijepo označen. Pauci imaju više očiju nego složene oči insekata i nemaju antene, ali imaju očite dlanove koji se koriste pri hranjenju, a koriste se tijekom reprodukcije kod mužjaka.

Ova ženka vrtnog kugla pauka čeka u središtu svoje mreže spremna pohađati svaki plijen koji bi se mogao uloviti u mrežu.

Na gornjoj fotografiji pauk se udaljava od središta kao odgovor na smetnju u mreži, ali u ovom slučaju potencijalni plijen je odletio, a da ga nije uhvatio, pa se pauk vratio u središte mreže gdje provodi većinu svog vremena vrijeme čekanja.

Neka pauci kugle pojedu središnji dio mreže noću i svako jutro ponovno izgrade taj dio weba.

Ova osa nije uspjela pobjeći s weba. Pauk ugrize predmete plijena i omota ih svilom kako bi ih imobilizirao, a obično se kasnije vraća da ih pojede.

Na gornjoj fotografiji pauk jede bubu koju je prethodno ugrizla i zamotala u svilu kad se zaglavila u mreži. Otrov koji ubrizgava u žrtvu imobilizira ga. Prije jela pauk ubrizgava probavnu tekućinu koja uključuje enzime koji tekućinu plijena ukapljuju, a koju pauk jede usisavajući tekućinu u želudac.

Mnogi pauci koji tkaju kružne (kuglaste) mreže uključuju cik -cak od guste svile poznate kao stabilimenta. Dva okomita zigzaga mogu se vidjeti na webu na gornjoj fotografiji. Nagađa se da stabilimenta ima nekoliko funkcija, koje mogu uključivati ​​pružanje kamuflaže ili ometanja pauka u središtu mreže, upozoravajući ptice da ne ulete u mrežu (i razbiju mrežu), privlačeći insekte da ulete u mreža kao stabilimenta reflektira ultraljubičasto svjetlo, a također i stvaranje stabilimenta može biti način taloženja viška svile i/ili poticanja proizvodnje više svile.

Većina pauka je bezopasna za ljude i treba ih, gdje je to moguće, neometano ostaviti. Složenost i inženjering mreža vrijedni su našeg divljenja. Većina pauka koristi vrtlarima jedući mnoge insekte i druga stvorenja koja vrtlari mogu smatrati štetočinama. U svakom slučaju, smatrao sam da je ovaj pauk elegantna i ukrasna prisutnost u vrtu, iako je iznenađujuće lako zanemariti.


Uobičajena vrsta pauka pronađena je u Viktoriji

Značka (lovac) pauk

Neosparassus diana

Stanište i biologija
Lovac sa značkom je noćno aktivan i povremeno dolazi u kuće, ali rjeđe od ostalih lovačkih pauka. Izvana se može pronaći u lovu na plijen na deblima drveća ili u lišću. Tijekom dana povući će se ispod kore drveta. Svileno utočište izgrađeno je u sličnoj situaciji za mitarenje i polaganje jaja. Neke vrste Neosparassus grade svileno utočište u lišću lijepljenjem nekoliko listova zajedno, dok druge grade plitke rupe. Ženku čuva vrećica za jaja, koja je pljosnata svilena kapsula. Tijekom tog razdoblja može biti prilično agresivna te će se pojačati u obrambenom prikazu ako bude isprovocirana. Mladi Neosparassus često su zelene boje.

Boja
Muški: Slično ženskom.
Žena: Od smeđe do narančaste ili ružičastosmeđe. Crna oznaka u obliku štita s dvije bijele mrlje na donjoj strani trbuha.

Oblik
Tijelo je spljošteno, mada manje od ostalih lovačkih skupina. Prva dva para nogu izrazito su duža od dva zadnja para.

Dužina tijela
Muški: 16 mm
Ženka: 20 mm

Vrsta weba
Ne gradi web.

Ugristi
Nisu zabilježeni ozbiljni simptomi od ugriza N. diana, ali poznato je da ugrizi drugih vrsta Neosparassusa uzrokuju opće simptome uključujući jaku lokalnu bol i oteklinu, znojenje, mučninu i povraćanje.

Pauk koji ispada ptica

Celaeniaiskopati

Stanište i biologija
Ovaj je pauk opisan kao majstor kamuflaže, a uzorak boje podsjeća na pticu koja pada. Još jedno uobičajeno ime za ovu vrstu je pauk smrtne glave, zbog navodne sličnosti boja tijela s lubanjom. Pauk koji ispušta ptice je sjedeći pauk koji se nalazi na listu ili je obješen ispod kutija za jaja. Kućišta jaja, do 13, velika su (promjera 12-14 mm), tamnosmeđe kugle s crnim križnim oznakama. Ovaj se pauk hrani noću, gotovo isključivo muškim moljcima. Sjedi s ispruženim prednjim nogama čekajući približavanje plijena. Pauk privlači moljca oslobađajući spolni feromon ili miris sličan onom koji proizvode ženke moljaca.

Boja
Muški: Slično ženskom.
Ženka: Tijelo mrljasto smeđe, crno i kremasto.

Oblik
Trbuh širok i trokutast, gornja se površina uzdiže prema par hrapavih grba prema stražnjoj strani, izrazito udubljena po središnjoj liniji. Noge sklopljene uz tijelo.

Crni kućni pauk

Badumna insignis

Stanište i biologija
Obično se nalaze oko zgrada u uglovima prozorskih okvira i vrata, u pukotinama od opeke, ispod streha itd. U prirodi se nalaze u rupama na deblima stabala, pukotinama u stijenama itd. Karakteristična čipkasta mreža s lijevcima ponekad se zbunjuje s paukom lijevkaste mreže, ali sve vrste paukova lijevkaste mreže koje se nalaze u Viktoriji grade svoja povlačenja na ili ispod razine tla. Crni kućni pauk je plašljiv pauk i obično će izaći iz svog povlačenja samo kad je plijen zapleten u mrežu. Plijen se zatim brzo zapleni i odvuče natrag u cijev. Mužjaci lutaju noću tijekom razdoblja parenja. Nakon parenja ženka polaže svoja jaja omotana svilom unutar cijevi. Maksimalni životni vijek je oko dvije godine.

Boja
Mužjak: Slično ženki, ali često blago blijedi.
Ženka: Cefalotoraks i noge sjajno crne, trbuh tuplji crn ili sivo-crn.

Oblik
Robustan, dlakavi pauk s tipično tupim, četvrtastim prednjim krajem cefalotoraksa.

Dužina tijela
Muški: 10 mm
Ženka: 20 mm

Vrsta weba
Čipkasti lim s jednim ili dva ulaza u obliku lijevka koji vode u cjevasto utočište.

Ugristi
Zbog svoje plašljive prirode ovaj pauk rijetko ujeda ljude, međutim, ugriz može uzrokovati opće simptome uključujući mučninu, znojenje, lokaliziranu bol i oteklinu.

Smeđi kućni pauk

Steatoda grossa

Stanište i biologija
Dvije su vrste Steatoda poznate pod imenom Brown House Spider. Ovi su Steatoda capensis (Hann) i Steatoda grossa (Koch). Ovaj se pauk često miješa s paukom s crvenim leđima koji ima sličan oblik tijela i strukturu mreže. Za razliku od pauka s crvenim leđima, smeđi kućni pauk nikada nema crvenu oznaku pješčanog stakla na donjoj strani trbuha. Smeđi kućni pauk (ponekad poznat i kao pauk iz ormara) često se nalazi u zatvorenim prostorima na tamnim mjestima, unutar ili ispod namještaja. Rijetko se na takvim mjestima nalazi pauk s crvenim leđima. Na otvorenom se smeđi kućni pauk može naći u šupama, ispod praznih posuda za biljke ili među općim smećem. Vrećica za jaja slična onoj crvenog leđa.

Boja
Mužjak: Manjeg tijela s dužim nogama sličnih boja kao ženke, osim bijelih oznaka.
Ženka: Ukupna boja tijela je smeđa do crna, tipično s tupim bijelim oznakama u obliku polumjeseca na vrhu trbuha, ponekad praćenim nekoliko dosadnih bijelih mrlja.

Oblik
Sličnog oblika pauku s crvenim leđima, s trbuhom u obliku graška i vitkim nogama.

Dužina tijela
Muški: 4 mm
Ženka: 10 mm

Vrsta weba
Zapetljana mreža s ljepljivim zahvatom pričvršćenim za podlogu.

Ugristi
Za razliku od pauka s crvenim leđima, ugriz smeđeg kućnog pauka nije smrtonosan, ali može uzrokovati glavobolju ili mučninu. Oko mjesta ugriza mogu se pojaviti mali mjehurići.

Tata pauk dugih nogu

Pholcus phalangioides

Stanište i biologija
Ovaj se pauk obično nalazi u zatvorenim prostorima na tamnim mjestima, poput vrata ili namještaja, napuštenih prostorija itd. Stare mreže često se vide u uglovima stropova. Vani se javlja u garažama i šupama, ispod verandi itd. Životni vijek može varirati od tri mjeseca do dvije godine, ovisno o temperaturi i opskrbi hranom. Hrana se sastoji od malih insekata, pauka, srebrnih ribica itd. Tata pauk s dugim nogama obično je povezan s ljudskim staništem i smatra se da je uveden u ovu zemlju. Žetve (Opiliones) ponekad pogrešno shvaćaju kao očeve paukove pauke, međutim, žeteocima nedostaje srednja stezanja tijela i rijetko se nalaze u zatvorenom prostoru, preferirajući vlažna područja vani. Jaja se drže zajedno u kružnom snopu s nekoliko svilenih niti i nose ih u ustima ženki do izleganja

Boja
Muški: Slično ženskom.
Ženka: Ukupna boja tijela blijedosmeđa do kremasta sa tamnijim oznakama na nogama i cefalotoraksu, ponekad s tamnijim oznakama na trbuhu.

Oblik
Prepoznatljiv po iznimno dugim i vitkim nogama i relativno malom tijelu.

Dužina tijela
Muški: 16 mm
Ženka: 20 mm

Vrsta weba
Čini zamršenu mrežu, promjera do 30 cm, unutar mjesta skloništa.

Ugristi
Relativno bezopasna lokalna reakcija ako postoji. Narodna predaja kaže da je otrov ovog pauka iznimno otrovan.

Vrtni pauk koji tka kugle

Eriophora biapicata

Stanište i biologija
Ovo je veliki robusni pauk koji gradi veliku, snažno izgrađenu kuglastu mrežu kako bi ulovio svoj plijen uglavnom letećih insekata. Web se obično gradi navečer, a ljudi ga ponekad neočekivano naiđu. Pauk počiva naopako u središtu mreže. U zoru se web često skida. Pauk zatim počiva na obližnjem lišću s uvučenim nogama i dobro je kamufliran. Jaja, koja ženka polaže u kasno ljeto do jeseni, zatvorena su u pahuljastu svilenu čahuru i pričvršćena na lišće. Životni vijek vrtnih orbicara je otprilike dvanaest mjeseci. Rasprostranjena je vrsta koja je zabilježena u svim državama osim u Tasmaniji.

Boja
Muški: Slično ženskom.
Ženke: Osnove nogu svijetlocrvene, ostatak nogu i cefalotoraks crvenkastosmeđi s dugim bijelim dlačicama. Trbuh smeđi, obično s tamnijim lisnatim uzorkom, a ponekad s bijelim mrljama ili prugama.

Oblik
Obično s trokutastim trbuhom s dvije uočljive grbe prema naprijed.

Dužina tijela
Muški: 18 mm
Ženka: 22 mm

Vrsta weba
Velika, snažno izgrađena kuglasta mreža.

Ugristi
Ugriz tkalja vrtnih kugli ne smatra se opasnim. Simptomi mogu uključivati ​​lokaliziranu blagu bol i oteklinu, mučninu i omaglicu.

Lovac Spider

Holconia immanis

Stanište i biologija
Ovaj lovac najčešće se nalazi u kućama, gdje noću lovi po zidovima i stropovima. Također povremeno ulazi u kabine vozila, izazivajući veliku uzbunu. U grmu se Holconia danju može skloniti ispod rastresite kore eukalipta. To je velika vrsta i kad se uznemiri, može se vrlo brzo kretati u bočnom smjeru. Hrana se sastoji od insekata i drugih beskralježnjaka. Vrećica za jaja je ravna, ovalna i izrađena od bijele papirnate svile. Najčešće se taloži ispod kore drveća. Životni vijek vrste je oko dvije godine.

Spider sa zamkom na vratima u Melbourneu

Stanwellia grisea

Stanište i biologija
Zbog svoje veličine, boje i velikih očnjaka, za ove se pauke često misli da su pauci u Sydneyu u obliku lijevka. Melbournski pauk sa zamkom na vratima uobičajen je pauk koji boravi u zemlji i na koji vikend vrtlar često nailazi prilikom kopanja tla ili pomicanja kamenja. I mužjaci i ženke kopaju svilene rupe do 40 cm duboko u mekoj zemlji. Unatoč referenci u uobičajenom nazivu, ulaz u paukovu jazbinu nema "vrata-zamke". Pauci se hrane noću, čekajući na ulazu u jazbinu da zaskoče insekte koji prolaze. Mužjaci napuštaju jazbinu kad sazriju i lutaju u potrazi za partnerom. Ovo roaming obično se događa u jesen ili početkom zime i može odvesti pauka na čudna mjesta, poput kuća, bazena itd. Pauci s vratima u zamci imaju dug vijek trajanja i mogu živjeti od 5 do 20 godina.

Boja
Mužjak: Slično ženki, samo što neki primjerci imaju zlatne dlake na cefalotoraksu.
Ženka: Cefalotoraks i noge smeđe, trbuh često blijedi s tamnim, pjegavim, rebrastim uzorkom na gornjoj površini.

Oblik
Veliki snažni pauci, mužjaci su općenito manjeg tijela i dugih nogu od ženki.

Dužina tijela
Muški: 25 mm
Ženka: 35 mm

Vrsta weba
Nekoliko niti svile zrači oko ulaza u rupu.

Ugristi
Zbog veličine očnjaka, pauk na vratima može nanijeti duboku, bolnu ranu, ali nije poznato da otrov uzrokuje medicinske probleme. Dva velika nastavka na repu pauka su prednji dijelovi, na kojima se otvaraju svilene žlijezde.

Miš pauk

Missulena bradleyi

Stanište i biologija
Poput pauka na vratima, mišji pauk živi u tunelima u zemlji. Za razliku od pauka Stanwellia, mišji pauci na ulazu posjeduju poklopac "vrata na zamku". Mužjaci su najaktivniji tijekom dnevnih sati rane zime, kada traže partnera. Blizak rođak, Missulena occatoria Walckenaer, javlja se u sušnijim zapadnim područjima Viktorije, a mužjaci ove vrste imaju izrazit crveni glavonožac i crni trbuh. Pauk mišjeg pauka očito se raspršuje po gossameru, tehnici koja je rijetka u migalomorfa. Uobičajeni naziv potječe od pogrešnog uvjerenja da je ovaj pauk iskopao jazbinu sličnu mišoj.

Boja
Mužjak: Cefalotoraks i noge sjajno crne, trbuh nešto bljeđi s izrazito blijedoplavkastim mrljama na gornjoj strani prema naprijed.
Ženka: Tamno smeđa do crnkasta.

Oblik
Prepoznate po velikom cefalotoraksu, staste noge i očna formacija raširile su se po prednjoj strani cefalotoraksa, a ne u kompaktnoj skupini kao u paukova vrata na klopci.

Dužina tijela
Muški: 15 mm
Ženka: 25 mm

Vrsta weba

Iako neki eksperimentalni dokazi ukazuju na to da je otrov mišjih pauka relativno otrovan, većina zabilježenih ugriza nije izazvala ozbiljne reakcije.

Crveni stražnji pauk

Latrodectus hasseltii

Stanište i biologija
Ovaj se pauk obično nalazi na otvorenom oko ljudskog prebivališta, na mjestima poput smeća, smeća, starih limenki, kontejnera, ispod i na stepenicama verande, te na ili ispod sjedala vanjskih WC -a! Namirnice za skladištenje i rabljeni namještaj potaknut će uzgoj ovog pauka. U prirodi se javlja ispod trupaca, kore, stranica stijena itd. Budući da pauk rijetko napušta svoju mrežu, nije vjerojatno da će ljudi biti ugrizeni osim ako se neki dio tijela (npr. Šaka) ne stavi u mrežu. Uvijek provjerite prije premještanja predmeta koji su neko vrijeme bili pohranjeni na otvorenom. Nosite rukavice pri čišćenju mjesta za smeće. Ženka proizvodi do deset blijedožutih vrećica jaja, svaka s približno 250 jaja. Ženke mogu živjeti dvije do tri godine, mužjaci oko 90 dana.

Boja
Muški: Obično bez crvenih oznaka. Tijelo je svijetlosmeđe s bijelim oznakama na gornjoj strani trbuha, a sa donje strane blijedo označeno pješčanim staklom.
Ženka: Tijelo i noge tamno smeđe do crne. Karakteristične crvene pješčane oznake na donjoj strani trbuha, obično također sa širokim, crvenim prugama na gornjoj strani stražnje polovice trbuha. Crvena traka ponekad slomljena. Maloljetnici se prepoznaju po bijelim oznakama na trbuhu.

Oblik
Karakterističan trbuh u obliku graška, duge vitke noge, mužjaci mnogo manji od ženki. Za više informacija pogledajte stranicu pauka muzeja Queensland.

Dužina tijela
Muški: 4 mm
Ženka: 10 mm

Vrsta weba
Zapetljana mreža s ljepljivim zahvatom pričvršćenim za podlogu.

Ugristi
Ugriz je vrlo otrovan i karakteriziran je intenzivnom lokaliziranom boli i oko mjesta ugriza. Ostali simptomi mogu uključivati ​​znojenje, mišićnu slabost, gubitak koordinacije i, u teškim slučajevima mučninu, povraćanje, konvulzije itd. Sljedeći opis enveomacije je iz Australijski životinjski toksini autor Struan Sutherland, 1983. Znakovi i simptomi: Uobičajeni slijed događaja nakon ugriza je sljedeći. Oštar bol pri ubadanju iglom gotovo je nepromjenjiv. Mjesto ugriza obično postaje vruće, eritem i edem se brzo razvijaju. Često se javlja lokalizirano znojenje. Oteklina je općenito ograničena na područje radijusa od nekoliko cm od mjesta ugriza, povremeno je izrazita. Približno pet minuta nakon ugriza počinje jaka lokalna bol koja se pojačava i povećava. U većini slučajeva bol je dominantni simptom pa je pacijent ponekad izbezumljen, pa čak i histeričan zbog svog intenziteta. Kretanje zahvaćenog ekstremiteta često značajno povećava bol. Tridesetak minuta nakon ugriza često se osjećaju bol i oteklina u regionalnim limfnim čvorovima. Ako se pojavi bol u trbuhu, pogoršava se kada su donji ekstremiteti ili genitalije ugrizli, vjerojatno zbog zahvaćenosti limfnih čvorova. Ponekad se jaka bol razvije u dijelovima udaljenim od mjesta ugriza, na primjer, u suprotnom udu ili suprotnoj strani trupa. U nekim slučajevima razvili su se neuobičajeni, čak i bizarni znakovi i simptomi. Bilo je tetaničnih grčeva, trnaca u zubima, oticanja jezika, infekcije na mjestu ugriza, konvulzija, prekomjerne žeđi, teškog proljeva, anafilaktičke reakcije na otrov, mrljastog osipa na licu, hemoptizije, dispneje, disurije, teškog trizma, uporne anoreksije, periorbitalni edem i/ili konjunktiva. Mrtva područja onoga što je opisano kao "bizarno znojenje" nisu neuobičajena pojava. Za dodatne informacije pogledajte


A. diadematus ima holarktičku rasprostranjenost, nalazi se u cijeloj Europi i Sjevernoj Americi, od južne Kanade do Meksika, te od Britanske Kolumbije do Newfoundlanda. [4] [5]

Boje pojedinih pauka mogu varirati od izrazito svijetložute do vrlo tamno sive, ali sve A. diadematus imaju pjegave bijele oznake po leđnom trbuhu, s četiri ili više segmenata koji tvore križ. Oznake nastaju u stanicama ispunjenim gvaninom, koji je nusprodukt metabolizma proteina. [6]

Odrasle ženke imaju duljinu od 6,5 do 20 mm (0,26 do 0,79 inča), dok se mužjaci kreću od 5,5 do 13 mm (0,22 do 0,51 inča). [7] Povremeno će ženka pojesti mužjaka neposredno nakon parenja. (Pogledajte video ispod.)

Noge pauka-tkalaca kugle specijalizirane su za predenje kuglastih mreža. Mreže grade veće ženke koje objese glavu dolje u središte mreže ili ostanu skrivene u obližnjem lišću, s jednom kandžom zakačenom za signalnu liniju povezanu s glavnom kuglom čekajući da smetnja signalizira dolazak plijena. Plijen se zatim brzo zagrize i zamota u svilu prije nego što se pohrani za kasniju potrošnju. Početni ugriz služi za paralizaciju plijena i minimiziranje opasnosti od uboda ili ugriza samog pauka, a tako ubrizgani enzimi započinju ukapljivanje unutarnjih struktura plijena.

Uz korištenje weba za hvatanje drugog plijena, pauci su također kanibali i međusobno plijene. Međutim, to se događa samo prije, tijekom ili nakon spolne aktivnosti. They attack based on their size, sexual experience and hunger levels.

A. diadematus is a reclusive creature and only bites humans if cornered or otherwise provoked. It responds to a disturbance by vibrating rapidly in its web until it becomes a blur, a reaction that is assumed to confuse potential predators. [8]


Around homes, orb spiders build their webs in the branches of trees and bushes, in gardens, and in the corners of doorways, porches, and decks. Orb spiders also commonly build their webs near or next to porch lights since the insects that they eat are drawn to light. They are the most common spider you'll find in your landscaping.

The best way to get rid of orb spiders from your home and property is with the help of a professional. At All-American Pest Control, we offer pest control services for orb spiders through our Perimeter Plus Pest Control program

Uvod

Silver Orb Weaving Spiders are recognised by their long, silvery bodies.

Identifikacija

Silver Orb Weaving Spidersare easily recognised by their silvery body, with yellow or green and black markings. They are long-bodied, long-limbed spiders. The abdomen often has rounded 'shoulder' humps that give these spiders their other common name of Humped Orb Weaving Spiders.

Stanište

The Silver Orb Weaving Spider is often found amongst understorey vegetation in moist forest and woodland habitats, including streamside and swampland vegetation.

Silver Orb-Weaving Spiders build small flimsy, horizontal webs among shrubs and grasses or over water.

Distribucija

Silver Orb Weaving Spiders are found throughout Australia.

Feeding and diet

Silver Orb Weaving Spiders remain in their webs during the day and capture flies and other small insects.

Predatori

Predators of orb weaving spiders include several bird species and wasps of the family Sphecidae. The wasps land on the web, lure the spider to the perimeter by imitating a struggling insect's vibrations, and then carry the spider away to be paralysed and stored as live food for their young.

Danger to humans

Orb weaving spiders are reluctant to bite. Symptoms are usually negligible or mild local pain, numbness and swelling. Occasionally nausea and dizziness can occur after a bite. Silver Orb Weaving Spiders have very small fangs and they are timid and reluctant to bite.


Can anyone identify this garden orb weaver spider? - Biologija

I am waiting eagerly to see if the golden orb weavers emerge again this season. It's a real mystery what is going on. The summer of 2011 brought an influx of golden orb weavers such as the town had never seen before. Last year, there were none. As spring is springing, the obvious question is: will they return? And why weren't they here last year? One theory is given below. This year will tell if it's right! And the other mystery - how did the daddy long-legs know about the feast on offer?

First, a recap. When we moved to Castlemaine in Central Victoria, Australia, in April 2011, there was a glorious adult female golden orb weaver (Nephila edulis, family Nephilidae) at the front door to greet us. So she was named Dobrodošli.

This is awe-inspiring, and a little bit funny, as you ended up with lots of spiders indoors, an event a spider lover like me finds wonderful. Finding out there is little or no research on a particular species is exciting, especially when one favors that species. As for the Daddy Long legs, I wonder if somehow scent is involved. Much of what spiders do is unknown, and that too, is exciting.

Thank you, ZBra. I am now back into blogging regularly as the season starts here. I can't wait to see if we get any Nephila this year.

Spiders are such amazing fun - and it is all there for free for anyone who just takes the time to get to know them!

Oh, and as for the scent attracting the daddy long-legs, that seems logical given they have chemical sensors in their hairs. But the juvenile Nephila are tiny, and the daddy long-legs must have been at least ten metres away, or I would have noticed them. You don't usually get five of them in close range. How strong is their scent detection? I have no idea, and doubt others do either. I'll check the gospel, Foelix's 'Biology of spiders' but I have read it thoroughly and certainly got no indication of long range scent detection. More research to be done.

I do adore watching a daddy long-legs pair on a web strumming out signals to each other. Is that language?

Hello, I live in Alabama, USA. The daddy long legs here are massive in size and regularly cluster in groups ranging from 3 to hundreds. It is quite a site to see. They seem to congregate as a family. They also clean the webs of other spiders by removing and eating the "leftovers", We also have many many large Golden Orb Weavers. Their common name here is Banana spiders. I have several living around the eaves of my home. And yes they are so fascinating to watch, along with all the other species that inhabit the corners and under eaves. I am starting to learn some of their names and habits. Was terribly afraid of them when we moved here but am now growing accustomed to them and even find myself feeling a little sad when one dies or disappears.

What you call daddy long-legs, we call harvestman. They have only a single body segment and don't make their own webs. I have seem a small cluster of very large daddy-long-legs / harvestmen in Texas, but nowhere near as large as you describe and I know can exist. I'd love to see it.

What we call daddy long-legs, you call cellar spiders. Very confusing!

I am delighted to hear about your changed attitude to your Golden Orb Weavers. The more you watch them, the more you will fall in love with them as individuals.

Thank you so much for writing!

It's been raining for 3 days now and I haven't seen my Golden Orb Spider. Is she missing or does she wait for the rain to stop before rebuilding?

I have noticed them disappear into the foliage during rain. Hopefully she will emerge when the rain is done. It is amazing how attached we can get to spiders we have been watching for a while. And Golden Orb Weavers are so stunning!

Please let me know if she emerges!

I have a garden orb weaver, that I have tended to in our kitchen just off the dinner table(which we never use to eat). She has built her web from the wall to the ceiling, to the large plant and the end of the table. I put strawberry top out in the Summer, that attract scores of fruit flies, she has moved her web higher and higher to catch them. When her web was a foot off the table, she didn't catch them, about a week of this she is now about 2 feet from the ceiling and catches quite a few a day. I will often herd them towards her web with a misty spray bottle. If I spray close to her, she climbs over to the plant and hides under a leaf or climbs high up to the top of her web near the wall in the corner. So I am guessing that is what she'd do if she were outside and it rained.
I have watched her since the first week of Summer back in June and it is now the first week of September and it has been both fascinating and a learning experience. From watching her feed and spinning her web, to molting about once every 3 weeks. She is quite big now. I named her Mickey.
Just tonight it appears she is laying her eggs as there is a small sac appearing right beside her, though it is difficult to say for sure until I can get a better look. I don't want to disturb her and it is difficult to see her up close, as the table is up against the back wall. I would have to climb on top and crawl over to see her up close. But if that is the case, then her life will be coming to a close and it will be time to move the sac outside, as I do not want baby spiders hatching in my kitchen. I will find a safe spot on my patio to put them. And hopefully one of her kids will join us next Summer. Truly a fascinating creature, that I have thoroughly enjoyed watching. Much to the puzzlement of my Teen aged Son, whom is not so fond of Spiders.

Thank you so much for such a wonderful story - and described so fully. This sounds delightful. The free entertainment on offer in nearly every house and garden is overlooked by almost everyone. I am so glad that you have been able to enjoy the fascination at such close range.

I've been watching a cross orb-weaver over the past couple months, she layed her eggs and passed away as of today when I checked. I nearly cried she was beautiful. I hope I get to see her babies hatch and grow. I'll be watching.

It is amazing how beautiful spiders are, especially the orb weavers, when you watch them over time and get to know the individuals. She had to die. It is the short lifespan they have. I do hope the young hatch and grow. They will ballon off and most - at least 99% - will not grow to maturity and breed. Any mature adult spider is a real survivor.

Let me know more of the saga if you see the young hatch! Thank you for the comment.

I've been lucky enough to have orbs in my garden for the last 10ish years. The same peach tree, each year, a large female grows and each year places her egg sac in the same peach tree before passing away. I still have the 'shell' of our first orb, we called her Shelby and each one following her has been Shelby2, Shelby3 and so on. We have a beautiful egg sac again in our tree and I'm always so impressed with these little wonders of nature. They have a place in my heart that's for sure.

I have enjoyed this read very much. I am an huge fan of spiders though must admit I know little about them. Will be sure to return regularly, thanks for sharing, Jilly

Delighted to meet you, Jilly. Thank you so much for your comments. I look forward to more!

This is interesting and terrifying. I have a garden spider across my front door and just saw the egg sac. You think I can safely move it before they hatch in the spring? I can avoid my front door for a few weeks and let her stay, but not for 8 months, and not when there is a spider explosion. (from Mississippi, USA)

The more you watch, the more they just become interesting and the terrifying goes.

I am not sure what you mean by 'garden spider' in Mississippi, but the orb weavers tend to die before winter. You can move the egg sac, but maybe wait until she has gone? Although, if it is a hassle, you can move her too. Just move part of the web and attach it to somewhere less obstructive. She will probably fix it up there rather than putting it back where it was.

All the best with it! Thank you for caring for the spider!

Hvala! They call them garden spiders here (among other things). She gets to stay, and I will wait til she dies to move the egg sac. I suspect there may eventually be other egg sacs since she eats a lot. We have Argiope aurantia here, at least that's what she appears to be. Hvala!

Ahh - Argiope, wonderful! I am jealous. Have fun watching her and then waiting for her spiderlings to hatch.

We have an Argirope aurantia in our back yard now. She came to us as an adult rescue spider. The family where she had been living called her HellSpawn, and the dad was going to try and poison her with WD--40. She had built her web across the shed, so she was not in a good place, and the family was afraid of her, which was worse. My daughter asked if she could take her home, and the family agreed. M caught her in a box and we release her in our backyard garden. Within a day she had made a lovely large web in a perfect place -- that was 3 weeks ago. She has caught a lot of bugs and my girls feed her grasshoppers from time to time to see her amazing spinnerets at work. She up, then disappeared today up by the eave if the house. We just checked in her now, and she has greatly deflated. Where she had been hanging by the eave we see an egg sac :) so That's what she was doing :)

What a great story! Hvala vam! Please tell your daughter that i think she is a hero!

Spiders are the best free entertainment (and education) in the world.

I just shared your comment with my daughter and she is very proud to be a Spider Hero :) We just came from the backyard where our Argirope has caught a grasshopper that is larger than her body. She is liquefying him now. Yesterday we learned a new thing: spiders can also eat prey whole. She caught a midge, and wrapped it lightly. We were wondering how she would liquefy it and the answer was she didn't: she crunched him up whole, like a taco. Just when you think you know your spiders, they surprise you!! :)

I am so pleased that your Argiope (is that her name as well as her genus?) is providing so much free and educational entertainment.

I think your new conclusion about eating food whole may be in error - or you are discovering new spider facts and your daughter needs to do a science project on it! Spiders will crunch up prey sometimes, but they still liquify what they are going to eat. They can only take in liquid and filter it finely as it goes into their mouths.

Are you getting plenty of photos? If so, please send me an email to l.kelly @ latrobe.edu.au (without the spaces). I'd love to see her and your daughter!

I work at a University in NW Florida and I have a beautiful female that lives right outside my office. Today she laid her egg sack!! I'm so excited I could burst! But I can't find any information on what happens to the female after she lays the sack, the general timeframe for the sack to hatch or approximately how many "grandbabies" I can be expecting. By any chance do you know any of this information?

I forgot to mention, she appears to be a "banana spider" or golden orb weaver.

It is so good to hear from you. I am so jealous. This sounds extraordinary.

I found information on the life cycle hard to find, but can tell you my observations. It partly depends on whether you are talking about a golden orb weaver or the yellow and black spider, Argiope, although I suspect the life cycle is fairly similar. Both are referred to as banana spiders.

A golden orb weaver egg sac is very golden. They are genus Nephila, as in the one above. In Florida, there is only one possible species, Nephila clavipes:

Is this the spider you have?

I expect she will then die with winter and her egg sac hatch later, but I am not sure. I would LOVE to hear more from you as you observe it, and see any photos. I would love to do a blog on your spider!

I submit my next book manuscript this week and then will get back to blogging spiders. I can wait!

Hi Lynne..I'm so glad I found your blog, I can't wait to delve into it some more! I live on the Florida panhandle so I guess our seasons are the exact opposite. Since late August I've had the privilege of caring for a beautiful golden orb weaver in my front shrubs. We had quite a few around here but I favored her. I fed her at least 2 grasshoppers everyday so in no time she was the biggest spider of them all. One day at the end of September I went out to feed her and she was super skinny so I figured she must have laid her egg sac sometime in the night. I was sort of sad because I have done a lot of reading on the orb weavers and I knew that meant her time was coming to an end. During the next couple of weeks I kept an extra close eye on her and she remained as lively as ever..also I never could find an egg sac. So I continued caring for her and eventually she became as fat as she was before. Then near the end of October we had our first cold spell, and very windy weather with hard rain. I knew she wouldn't make it. But the next morning I found that she had relocated during the storm higher up in a tree next to the shrubs (about eye level), and I couldn't find any of the other orb weavers. I wonder if she survived because she was so well-fed? Every time we had a cold night or a storm I would go out expecting not to see her and she would surprise me every time. So yesterday, November 18th, was a cold windy raining buckets kind of day, and this morning, she is gone. I never thought I'd be sad at the loss of a spider but I found her so amazing, therapeutic to watch, even. I see her egg sack now, under a leaf that was near her web. I'm not sure if she laid it that first time or sometime after, or if there was more than one sac, or what..It doesn't get as cold here as it does some places, but throughout the winter we will have some freezing weather. I don't see how that sack will survive. Do you think I should try to relocate it? And if so, where would you suggest? Do the sacks survive freezing weather? I'd love and appreciate any information you could give me. I have some pics and video of her but I don't think I can add it to the comment.
I hope to hear back from you!
❤ Poppy

Thank you so much for such a wonderful comment. Isn't it wonderful to follow the lives of individual spiders?

I have now sent off the manuscript for my next book to my publisher and can get back to blogging my precious spiders! Your post has inspired me to get back to taking the torch and camera out each night.

It does sound like your favourite (does she have a name?) has survived because she is so well fed and smart enough to relocate.

I know all about the sadness of losing a spider. I was devastated when I lost my wolf spider, Theresa, one of the stars of my book. I had taken hundreds of photos of her and she was quite used to my presence. She was part of my daily life. I even watered her when the weather was very hot and dry and she came up to drink the droplets every time.

The sac will survive, I assume, or there wouldn't be any spiders in the area. I have relocated a scam successfully, but I am not sure if it is necessary.

I'd love to see the pics and video. Then I can post them as a proper post. Can you send them to me at:

I am really keen to hear more of the story! Two correspondents from Florida now! Vau!

I'm so happy to hear my comment inspired you! My spider had the most common spider name you could imagine..I just couldn't help but to name her Charlotte, lol. Her tiny boyfriend was George. My husband swears he can't remember a year that we haven't had them on our property so I pray that I have another pet next year. He talked me out of relocating the sac, although I've been so tempted. We had our first cold, cold night and some crazy wind this year, but hubby keeps telling me that Charlotte knew what she was doing. I'm really glad I got some pics of her. I'm going to go through my carousel and find some of the best to send to you. Thank you so much for the reply and I look forward to reading your book!
Your friend, Poppy

My little garden orb weave is out at night and growing but I cannot find her resting place during the day, even though I now know what side of the web she is coming from. She is so well hidden. I can't deadhead the roses until I find her! I'd hate to prune her off the plant!

Thank you so much for the videos and photos. I have taken a few still from the videos and will blog about them. Unfortunately things were a bit blurry - but that was because of the wind. How amazing that she was feeding and wrapping her prey in that wind. The silk is so flexible!

I thought that I could see two females in the images. The males are much smaller, and the one against the blue sky and the one wrapping her prey appear to both be female. They look like Nephila calvipes to me.

I'll do a blog post about her and Rose and Mysti as well.

Maybe you can comment on that and tell me more!

I'm glad to see I'm not alone. We live in Michigan and we currently have a golden orb weaver on the front door of our old farmhouse. It has been in the upper corner of the brick door arch since early October and we are assuming female, so like the family above, we also named her Charlotte. The weather has been changing rapidly and she has, so far, survived strong 50+ mph wind gusts, rain storms, snow, etc. She is rather chubby and has grown on us. We have discussed whether we should bring her in for the winter and take care of her with the intention placing her back on the porch when spring arrives. However, I'm now concerned of the potential for babies. We've never seen a mate, but we are reading they can still lay an egg sac? I feel guilty just letting her die knowing harsher weather will surely arrive soon. I'm also going to call our local U of M Nature Center in hopes they'll accept her if we deliver. Any thoughts or leads to help? Thanks, Rose

It is so good to hear from you. When I was writing my spiders book, I interviewed the guys who did the animation of Charlotte for the film and told them what a huge impact they had on the attitude to spiders. They were delighted by that effect of their work.

I am afraid that her dying once she's laid the egg sac is the way of the world. I'd be really keen to hear of any alternatives. Your Charlotte is a real survivor - incredible aren't they?

The egg sac will almost certainly survive. If they didn't, there would be any adults for the following season. I would be interested to know how the Nature Center responds.

As for the male, they are much smaller that the female. Although in most spider species, the males can live on after breeding, that isn't always the case with golden orb weavers. The female will often eat them after mating.

I have photos now from Poppy. Would love to see any you have as well.

Thank you again for writing and please send updates!

Hi Lynne and Happy New Year! I am your third Floridian! I love this post. You have a heart of gold to save all those babies. I am in a situation myself. I took down the sac of my friend who lived between the porch posts this summer (a nephila clavipes), it was on the porch ceiling and would have been destroyed during pressure washing. I took it down on the last day of the year and had it outdoors in a glass year with a breathable lid while trying to decide where to put it. Today the nymphs hatched!! They picked the first freeze of the season!! When I saw they were coming out (at sundown), I put the sac in a shallow dish of leaf litter on a table on the porch. About thirty of them were in the jar but stuck in a bit of condensation. I brought the jar inside and they have all dried off an are trying to exit the jar. Should I put them outside tomorrow even though the high will be about 55F? I am worried they won't survive as it will probably freeze tomorrow as well (predicted low is 35F tomorrow but you never know). Do you have any thoughts for me? I have emailed the local extension office for the university here and set a question in BugGuide.net, but an internet search did not illuminate questions on nymph survival in freezing conditions of day of hatching. :( I hope the best for my little friend's babies but am at a loss as to how to proceed.

Happy new year to you and all spider-lovers in Florida.

What a fascinating story. If I can do my calculations right, 35 is close to freezing, about 1.7 deg C. That is cold, but I am pretty sure they can survive it. I am very keen to know what BugGuide or anyone else suggest. I suspect Nature knows better than we do.

Unfortunately, the reality is that most will not survive whatever you do. If they do their first moult when all confined together, they will start feasting on sibling stew and most will die anyway. Not pretty!

Sorry, but my advice is that they need to be free to leave. PLEASE let me know what happens!

Thanks for your response, Lynne,

I put the dish with the leaf debris and the sac in a tall brown paper grocery bag the garage and the little jar with the others laid on side with opening toward the sac. The garage was a little warmer than the outdoors. Just checked and no one is doing much, littles were still in the jar and no one else has exited the sac. the jar occupants were all on a couple of paper towel pieces so I gently dumped them into the litter by the sac. Maybe too cold for them to move much? It is about 45-50 in the garage. Maybe keep them there until they start to move and then put them outside? I have not heard back from anyone else. No moulting yet.

I will let you know what happens, a bunch of thanks once again!

Looking forward to the next instalment!

Hi, I'm Edie from Folsom, La. and enjoy my nephlia clavipes, but have only seen one Agriope Aurantia several years ago and no more since. I have eight acres and also more Nephlia clavipes than I can count, but treasure each one. So far I have been unable to locate an egg sac, but will keep looking and would like specific information on how to preserve it over the winter and the best possible release of the babies in the early spring. Most of my females have a male in the web with them or one close by. Thank you so much for all the information you have shared. I lost all I could find the year after the Katrina hurricane, but the population has rallied. Edie Stumpf

HI Edie. Thank you for writing!

I would adore to have more Nephila than I could count. In fact, one would be nice. We have had almost none in the area ever since the burst of activity when I took the photographs above a few years ago. But we have just had a wetter winter after years of drought, so maybe they'll be back this year. I also hope we'll have Argiope. In both, of course, we have different species but they are very like yours.

I find the egg sacs very hard to find. I only collected the egg sac because it was attached to a structure which was going to be moved. I think that wherever the spider leaves it is the most likely to be successful. If you want to observe it by moving it, then somewhere outside would be best. Inside would be too dry and warm.

I am so pleased they have rallied after the cyclone. Please let me know if you find the egg sac, and any other observations.

Hi don't know if you still on here. I have had 4 golden orb spiders in my yard. The females kept traveling around the yard and i was following them with the movements, very hard when they decide to move over night and the hunt begins to look for them all the time. I found 2 sacs of eggs in my tree and didn't think they left anything, but to my surprise while pruning my tree i found them and did a Google search and came to your blog. Thank you for putting up pictures of them so I know what they actually look like. I will be looking out for when the babies do come out of the sac. I have never had any golden orb spiders in my yard before. Only this year I saw the 4. But after the storms we had in the Cape this winter, I haven't found any of them. Cheers Chants

Yes, I am still here. Since the Spiders books was published, I became obsessed with the topic of my PhD and most recent two books. But I still adore my spiders as much as ever. I hope to have more time to big here now that my new book , The Memory Code, is out.

How wonderful to have 4 golden orb weavers. I wonder why they are moving. Mine usually don't do that. It sounds like an adventure to find them each day! It's great that you found the egg sacs. The one in these photos are the only ones I have ever found in my own yard.

The numbers each year do seem to vary a lot, but I am not sure that any studies have been done which know why. I have asked arachnologists and they all acknowledge that the numbers can vary hugely year to year, but don't know why. They suspect it is to do with weather.

I have no idea where you are. The Cape could be in Australia or South Africa or lots of other places. Where are you?
