Isicabucabu esine-spiked (uGasteracantha cancriformis) singaphansi kwesigaba sama-arachnids.
Ukusabalala kwesicabucabu se-orb-web esine-spiked.
Isicabucabu okuthiwa i-orb-web spiked sitholakala ezingxenyeni eziningi zomhlaba. Kutholakala eningizimu ye-United States kusuka eCalifornia kuye eFlorida, kanye nase-Central America, eJamaica naseCuba.
Indawo esihlala kuyo isicabucabu okuthiwa i-spiked - orb eluka
Izicabucabu ezi-orb-web ezinameva zihlala emahlathini nasezivandeni zezihlahla. Izicabucabu zivame kakhulu ezihlahleni ezisawolintshi eFlorida. Zivame ukutholakala ezihlahleni noma ezungeze izihlahla, izihlahla.
Izimpawu zangaphandle zesicabucabu esikhanyisiwe - iwebhu yewebhu.
Ku-spiny orb eluka izicabucabu, kuboniswa ubukhulu besimo sobulili ngobukhulu. Abesifazane bano-5 kuya ku-9 mm ubude no-10 kuya ku-13 mm ububanzi. Abesilisa bano-2 kuya ku-3 mm ububanzi futhi bancane kancane ngobubanzi. Izinsipho eziyisithupha esiswini zikhona kuwo wonke ama-morphs, kepha umbala nokuma kuncike ekuhlukeni kwendawo. Izicabucabu eziningi zinamabala amhlophe ngaphansi kwesisu, kepha ngaphezulu kwe-carapace kungaba bomvu, o-orenji noma ophuzi ngombala. Ngaphezu kwalokho, ezinye izicabucabu ze-spb orb-web zinemilenze enemibala.
Ukukhiqizwa kabusha kwesicabucabu okuthiwa i-spiked - orb eluka.
Ukukhiqizwa kabusha kwezicabucabu ze-spb orb-web kuye kwabonwa ekuthunjweni. Ukukhwelana kwenzeka endaweni yelabhorethri kunowesifazane oyedwa kuphela nowesilisa oyedwa. Kucatshangwa ukuthi uhlelo olufanayo lokumatanisa lwenzeka emvelweni. Kodwa-ke, ososayensi abaqiniseki ukuthi lezi zigcawu zinesoka elilodwa noma isithembu.
Izifundo zaselabhoratri zokuziphatha kokukhwelana zibonisa ukuthi abesilisa bavakashela iwebhu yabesifazane futhi basebenzise isigqi se-4-beat isigubhu ukuheha isicabucabu.
Ngemuva kokusondela kaningi ngokucophelela, owesilisa usondela kowesifazane nabalingani bakhe naye imizuzu engama-35 noma ngaphezulu. Ngemuva kokukhwelana, owesilisa uhlala kwiwebhu yabesifazane; ukukhwelana kungaphindwa.
Insikazi izalela amaqanda ayi-100 kuya kwangama-260 emgodini obekwe ngaphansi noma ohlangothini olungenhla lwamaqabunga eduze kocingo lwesicabucabu. Umfece unesimo se-oblong futhi wakhiwa yimicu emincane evulekile evulekile; unamathele ngokuqinile ekhasini leqabunga usebenzisa idiski ekhethekile. Ukusuka ngenhla, umfece uvikelekile ngesinye isembozo semicu eyishumi eqinile, eqinile, eluhlaza okotshani. Le micu yakha imigqa ehlukahlukene yobude obude kukhukhunathi. Ngemuva kokubeka amaqanda, insikazi iyafa, eyeduna ifa ngisho nangaphambi kwalokho, ezinsukwini eziyisithupha ngemuva kokukhwelana.
Izicabucabu ezincane ziphuma emaqandeni futhi ziphila ngaphandle kokunakekelwa ngabantu abadala; zihlala endaweni izinsuku ezimbalwa ukuze zifunde ukuhamba. Bese izicabucabu zihlakazeka entwasahlobo, lapho sezikwazi ukweluka iwebhu zizalele amaqanda (abesifazane). Kokubili abesilisa nabesifazane bayakwazi ukuzala phakathi kwamasonto amabili kuya kwayisihlanu ubudala.
Izicabucabu ezi-spiked - izicabucabu ze-orb-web azihlali isikhathi eside. Isikhathi sokuphila sifushane futhi sihlala kuphela kuze kube sekuzalaneni.
Ukuziphatha kwesicabucabu esikhanyisiwe - iwebhu yewebhu
Ukukhiqizwa kabusha kwezicabucabu ezinameva - ukwelukwa kwe-orb kwenzeka ekupheleni konyaka. I-spider web yakhiwe ikakhulu ngabesifazane njalo ebusuku; abesilisa bavame ukulenga kolunye lwezintambo zesicabucabu eduze kwesidleke sowesifazane. Isicupho sesicabucabu silenga engeli elincane kulayini ojikelezayo. Inethiwekhi uqobo iqukethe isisekelo, esakhiwa ngentambo eyodwa eqondile, ixhunywe kulayini wesibili oyinhloko nezintambo ezisabalalayo.
Isakhiwo sakha i-engeli eyakhiwe ama-radii amathathu ayisisekelo. Kwesinye isikhathi, iwebhu inama-radii ayisisekelo angaphezu kwamathathu.
Ngemuva kokwakha isisekelo, isicabucabu siqala ukwakha irediyasi enkulu engaphandle bese siqhubeka nokufaka imisebe yesibili enamathiselwe emoyeni.
Abesifazane bahlala bodwa kumaphaneli ahlukene. Kufika kwabesilisa abathathu kungalenga emicwini kasilika eseduzane. Izinsikazi zitholakala noma ngasiphi isikhathi sonyaka, kepha zitholakala kakhulu kusuka ku-Okthoba kuya kuJanuwari. Abesilisa babanjwa ngo-Okthoba nangoNovemba. Ama-spider webs alenga amamitha ayi-1 kuye kwayi-6 ngaphezulu komhlaba. Umsebenzi wenziwa emini, ngakho-ke lezi zigcawu ziqoqa kalula inyamazane ngalesi sikhathi.
Ukudla okunomsoco kwesicabucabu okuthiwa i-spiked - orb weaving.
Abesifazane bakha iwebhu abayisebenzisayo ukubamba inyamazane. Bahlala kuwebhu uhlangothi lwangaphandle lomzimba lubheke phansi, balinde inyamazane kwi-disc emaphakathi. Lapho isinambuzane esincane, impukane inamathela kuwebhu, isicabucabu sinquma ngokunembile ukuma kwalowo ohlukunyeziwe bese sigijimela kuso ukuze silume, bese sisidlulisela kudiski emaphakathi, lapho sidla khona isisulu.
Uma isisulu sincane kunesicabucabu, simane sikhubaze lesi sinambuzane esibanjiwe bese sisishukumisela ukuba sidle. Uma inyamazane inkulu kunesicabucabu, okokuqala inyamazane ifakwa kuwebhu, bese kuphela lapho idlulela kudiski emaphakathi.
Uma kwenzeka izinambuzane eziningana zihlangana nayo yonke inethiwekhi ngasikhathi sinye, khona-ke isicabucabu esinameva - i-orb eluka - sizothola zonke izinambuzane futhi sizikhubaze. Uma isicabucabu sondliwe kahle, khona-ke izisulu zilenga kuwebhu isikhathi esithile bese zidliwa ngokuhamba kwesikhathi. Isicabucabu esine-spiked - iwebhu yewebhu imunca okuqukethwe uketshezi kwesisulu sayo, izitho zangaphakathi ziyoncibilika ngaphansi kwethonya lobuthi. Izidumbu ezomile ezimbozwe ulwelwesi olunezinwele ziyalahlwa enetheni. Imvamisa izidumbu ezigqunyiwe zilele zizungeze ubulembu. Isicabucabu esine-spiked - ukwelukwa kwe-orb kudla izimpukane ezimhlophe, amabhungane, amabhu nezinye izinambuzane ezincane.
Isicabucabu esine-spiked - i-orb eluka yathola igama layo ngokutholakala kwameva ngemuva. Lameva ayisivikelo ekuhlaselweni yizidlakela zomsebenzi. Lezi zigcawu zincane kakhulu futhi azibonakali neze emvelweni, okwandisa amathuba azo okusinda.
Indima ye-ecosystem yesicabucabu esine-spiked ukweluka kwe-orb.
Isicabucabu esine-spiked - i-orb eluka izingela izinambuzane eziningi ezincane ezikhona ezitshalweni, ezingadini nasezivandeni zasekhaya. Kuyasiza ukulawula inani lezinambuzane ezinjalo.
Okusho umuntu.
Isicabucabu esine-spiked siyinhlobo ethokozisayo yokufunda nokutadisha. Ngaphezu kwalokho, ihlala ezihlahleni ezisawolintshi futhi isiza abalimi ukulawula izinambuzane. Kososayensi bezofuzo, lesi silwane esincanyana siyisibonelo sokubonakaliswa kokuhlukahluka kwezindawo zokuhlala ezahlukahlukene. Abaphenyi bakwazi ukutadisha ukuhlukahluka kwemibala yezakhi zofuzo ezishintsha kwizicabucabu ezinoshintsho olubukhali emazingeni okushisa ambient, lokhu kuyisibonelo sokubonakaliswa kokuzivumelanisa nezimo ezithile. Isicabucabu esine-spiked - ukwelukwa kwe-orb kungaluma, kepha akulimazi lutho kubantu.
