Isicabucabu esine-spiked (Gasteracantha cancriformis) singesama-arachnids.
Ukusakazeka kwesicabucabu esikhanyisiwe.
Isicabucabu esisikiwe sisatshalaliswa ezingxenyeni eziningi zomhlaba. Kutholakala eningizimu ye-United States kusuka eCalifornia kuye eFlorida, kanye nase-Central America, eJamaica naseCuba.
Indawo yokuhlala isicabucabu esikhanyisiwe.
Isicabucabu esine-spiked sitholakala emahlathini nasezivandeni zezihlahla. Abantu abaningi bahlala ezihlahleni ezisawolintshi eFlorida. Zivame ukuhlala ezihlahleni noma ezungeze izihlahla, izihlahlana.
Izimpawu zangaphandle zesicabucabu esikhanyisiwe.
Ubukhulu besicabucabu esinsikazi esine-spiked busuka ku-5 kuye ku-9 mm ngobude futhi kusuka ku-10 kuye ku-13 mm ububanzi. Abesilisa bancane, bayi-2 kuya ku-3 mm ubude futhi bancane kancane ngobubanzi. Izinsipho eziyisithupha zikhona esiswini. Umbala wekhava le-chitinous uncike endaweni yokuhlala. Isicabucabu esine-spiked sinezimagqabhagqabha ezimhlophe ngaphansi kwesisu, kepha emuva kungaba bomvu, owolintshi noma ophuzi. Ngaphezu kwalokho, izitho ezinemibala zitholakala kwabanye abantu.
Ukukhiqizwa kabusha kwesicabucabu esikhanyisiwe.
Ukukhwelana ngezicabucabu ezicwebezelayo kwakubonwa kuphela ezimweni zelabhoratri, lapho kwakukhona khona owesifazane nowesilisa oyedwa. Kucatshangwa ukuthi ukukhwelana kwenzeka ngendlela efanayo emvelweni. Kodwa-ke, ososayensi abaqiniseki ukuthi lezi zilwebu zodwa yini.
Izifundo zaselebhu zokuziphatha kokukhwelana zibonisa ukuthi abesilisa bavakashela izintambo zesicabucabu zesifazane futhi basebenzise isigqi sokudlidliza esingu-4x kuma-webs kasilika ukuheha abesifazane. Ngemuva kokusondela kaningi ngokucophelela, owesilisa usondela kowesifazane nabalingani naye.
Ukukhwelana kungahlala imizuzu engama-35, bese owesilisa ehlala kuwebhu yabesifazane.
Isicabucabu sizalela amaqanda ayi-100 kuya kwangu-260, bese sona siyafa. Ukuze amaqanda akhule, insikazi yakha umucu wesicabucabu. Umfece utholakala ngezansi, kwesinye isikhathi ohlangothini olungenhla lweqabunga lomuthi, kodwa hhayi esiqwini noma ngaphezulu kwegatsha. Umfece unesimo esiyindilinga futhi wenziwe ngemicu emihle elukiwe eboshelwe ngokuqinile engxenyeni engaphansi yamaqabunga ene-disk eqinile. Amaqanda atholakala ocingweni oluxekethile, olunesiponji, nolunamathele emicu ephuzi nomhlophe egcinwe ndawonye nge-disc kolunye uhlangothi. Ukusuka ngenhla, umfece umbozwe ngongqimba lwemicu eminyene eluhlaza, eqinile, neluhlaza okotshani.
Le micu yakha imigqa ehlukahlukene yobude obude emzimbeni kakhokho. Isakhiwo siqedwa ngendwangu yembozo embozwe, engaphezulu kwenqwaba yobulembu, ehambisana neqabunga. Amaqanda akhula phakathi nobusika. Izicabucabu ezichanyuswayo zifunda ukuhamba kahle izinsuku ezimbalwa, bese zisakazeka entwasahlobo. Izinsikazi ezincane ziluka ama-webs futhi zibekele amaqanda, kuyilapho abesilisa bedingeka kuphela ekukhulelweni. Kokubili abesilisa nabesifazane bayakwazi ukuzala phakathi kwamasonto amabili kuya kwayisihlanu ubudala.
Ngokwemvelo, lolu hlobo lwesicabucabu aluhlali isikhathi eside kakhulu. Ngempela, baphila kuze kufike ekuzalelaneni, okuvame ukwenzeka entwasahlobo ngemuva kobusika. Izinsikazi zifa ngokushesha ngemuva kokuluka umfece nokubeka amaqanda, kuthi ezesilisa zife ngemuva kwezinsuku eziyisithupha.
Izici ukuziphatha isicabucabu spiked.
Izicabucabu ezinamabala zakha inetha lokuzibamba njalo ebusuku, zivivinya amandla ezintambo zesicabucabu. Izintambo zesicabucabu zelukelwa ikakhulukazi ezinsikazi ezindala, ngoba ngokuvamile abesilisa bahlala entanjeni eyodwa yobulembu besidleke sowesifazane. Isicabucabu silenga kuwebhu ngezansi, silinde isisulu saso. Inethiwekhi uqobo lwayo yenziwe ngengqikithi enentambo eyodwa eqondile. Ixhuma kulayini oyinhloko wesibili noma ngasogudlwini olukhulu lwendawo. Kuzona zozimbili izimo, izinkontileka zesakhiwo ziye ekhoneni zenze ama-radii amathathu amakhulu. Kwesinye isikhathi inethiwekhi inemisebe eyedlula emithathu.
Ngemuva kokudala isisekelo, isicabucabu sakha iwebhu yangaphandle, etholakala ngokuvunguza.
Zonke izintambo zesicabucabu zixhunywe kwi-disc emaphakathi. Kunomehluko phakathi kobukhulu bezintambo ezinkulu nezincane.
Abesifazane bahlala bodwa kuma-web spider ahlukene. Kuze kufike emadodeni amathathu angahlala ezintanjeni zikasilika eziseduze. Izinsikazi zitholakala noma ngasiphi isikhathi sonyaka, kepha ikakhulukazi kusukela ngo-Okthoba kuya kuJanuwari. Abesilisa bahlala phakathi kuka-Okthoba noNovemba. Ama-spider webs alenga amamitha ayi-1 kuye kwayi-6 ngaphezulu komhlaba. Izicabucabu ezinameva ziyasebenza emini, ngakho-ke ziqoqa kalula inyamazane. Izicabucabu ezinamaphiko zithola igama lazo eziqhameni ezincanyana ezingxenyeni engenhla ye-carapace. Lameva avikela ekuhlaselweni yizilwane. Ngaphezu kwalokho, osayizi abancane bayabasindisa ekuzidleni, ngenxa yokuthi izidumbu azikwazi ukuzithola njalo emaqabungeni ezihlahla. Amaqanda esicabucabu avame ukulinyazwa ama-parasitoid avela eminyozweni nasezimpukaneni.
Ukondla isicabucabu esikhanyisiwe.
Izicabucabu zesifazane ezifuthwayo zakha iwebhu eziyisebenzisayo ukubamba inyamazane. Insikazi ihlala kuwebhu, ilinde inyamazane kwi-disc emaphakathi.
Lapho isinambuzane esincane sibanjwa kuwebhu, sigijimela kuso, sizwe ukungabaza kwesisulu.
Ngemuva kokuthola indawo yayo ngqo, iluma, ifake into enobuthi. Ngemuva kwalokho owesifazane udlulisela isisulu esikhubazekile kwi-disc emaphakathi. Uma inyamazane incane ngosicabucabu ngosayizi, isivele siyikhubaze, bese imunca okuqukethwe ngaphandle kokuyifaka kuwebhu. Uma isisulu esibanjiwe sikhulu kunesicabucabu, khona-ke ukupakisha nokuhambisa kwi-disc emaphakathi kuyadingeka.
Kwesinye isikhathi izinambuzane eziningana zingena enetheni ngasikhathi sinye, lapho-ke isicabucabu kufanele sithole zonke izisulu bese sizikhubaza. Isicabucabu asibabekezeleli ukuze sibamunce ngokushesha, kodwa sivela kuphela uma kudingeka. Isicabucabu esine-spiked singadla kuphela okuqukethwe kuketshezi okuphakathi kwesisu saso. Isembozo se-Chitinous, esidliwe yizinambuzane, silenga kuwebhu esimweni sokumiswa. Ukudla okuyinhloko kwezicabucabu: izimpukane zezithelo, izimpukane ezimhlophe, amabhungane, amabhu nezinye izinambuzane ezincane.
Indima ye-ecosystem yesicabucabu esisikiwe.
Izicabucabu ezinameva zizingela izinambuzane ezincane ezilimaza amaqabunga ezitshalo futhi zilawule inani lezinambuzane ezinjalo.
Okusho umuntu.
Lesi spider esincane siyinhlobo ethokozisayo yokufunda nokutadisha. Ngaphezu kwalokho, isicabucabu esisikiwe sibheka izinambuzane ezincane ezihlahleni ezisawolintshi, sisiza abalimi ukuqeda izinambuzane. Lolu hlobo lwesicabucabu lwakha amafomu e-morphological ahlukahlukene ezindaweni ezahlukene. Abaphenyi bangafunda ukuhlukahluka kofuzo, imiphumela yokushintsha kwezinga lokushisa nokuzivumelanisa nezindawo ezithile zokuhlala.
Isicabucabu esine-spiked singaluma, kepha ukulunywa akulimazi kangako kubantu.
Abantu bayasatshiswa yimikhaba enamabala ekwazi ukunwaya isikhumba lapho ihlangana nesicabucabu. Kepha ukubukeka okwesabisayo kuyacasulwa izinzuzo ezilethwa yizicabucabu ezinesipikili ekulondolozeni izitshalo zikawolintshi.
Isimo sokongiwa kwesicabucabu esikhanyisiwe.
Isicabucabu esine-spiked sitholakala ngobuningi kuyo yonke inkabazwe yasentshonalanga. Lolu hlobo alunaso isimo esikhethekile.
