Darwin's bark spider
IrarumaDarwin's bark spider is an orb-weaver that builds the largest orb webs ever seen. It lives in the forests of Madagascar, where it hangs its web over rivers and lakes. Scientists found it in 2009, and it has unusually tough silk.1
Uko wayimenya
- Females are largely black, with white hairs on the body and legs.1
- The top of the front body section has two pairs of raised humps, one at the sides and one towards the back.1
- Females are about 1.8 to 2.2 cm long, while males are around 0.6 cm.1
- Males are redder and lighter brown, with white hairs and red, hairless leg segments (femora).1
- Webs are very large, up to 2.8 square metres, and are strung over water.1
Ikunze kwitiranywa na: Other Caerostris species live in the same region of Madagascar. Darwin's bark spider has clearly separated epigynal chambers (parts of the female's genital plate) with a pair of hooks at the back, which the other species from the region do not have.1
Imbaraga z'ubumara

Akaga ku bantu: YorohejeNko guterwa urubori n'uruyuki cyangwa munsi yaho. Mu by'ukuri ntacyo itwaye abantu.
Niba iruma
- Oza aho yarumye kandi uhashyire agapaki k'urubura kubera ububabare. Shaka ubufasha bwa muganga niba ububabare bukabije, bukwirakwira cyangwa umuntu yumva atameze neza.
Buri gihe banza uhamagare nimero y'ubutabazi (112, 000, 911). Izi ni inama rusange z'ubutabazi bw'ibanze, si inama za muganga. Ibanze by'ubutabazi bw'ibanze
Irinde akaga
- Ntuzigere ukora, ufata cyangwa ushotora inyamaswa yo mu gasozi, nubwo yaba ntoya, kandi nubwo yasa n'isinziriye cyangwa yapfuye.
- Yihe umwanya. Niba uhuye n'imwe, tuza, usubire inyuma buhoro buhoro kandi uyireke yigendere.
- Niba imwe ikurumye: tuza, ntunyeganyege, hamagara nimero y'ubutabazi (112, 000, 911) cyangwa ujye ku bitaro vuba. Ibuka uko yasaga, ifoto irafasha.
Ntigushakisha ngo ikugirire nabi. Ikoresha ubumara bwayo kugira ngo ifate ibyo kurya cyangwa yirinde, kandi ikunda cyane kwihisha. Ibindi ku kwirinda

Ibintu by'ukuri
Its silk is the toughest biological material ever studied. It is over ten times tougher than a similar amount of Kevlar.1
Its web is the largest orb web ever observed, covering up to 2.8 square metres. Its bridge lines can span up to 25 metres.1
The spider uses a set of web-building behaviours that are unknown in other spiders. It releases bridge silk into the air so the wind carries it across the water.1
Females are much larger than males, sometimes many times heavier. This is one of the most extreme size differences between the sexes in spiders.1
Flies that feed on its catches have been found living alongside it, and the spider sometimes chases them away.1
