Darwin'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

Engeri y'okukitegeera

  • 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

Kitera okutabulwa ne: 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

Bwe kiruma

  • Naaza ekifo ekirumiddwa era okiteekeko ayisi olw'obulumi. Funa obuyambi bw'abasawo singa obulumi bungi, busaasaana oba omuntu awulira bubi.

Bulijjo sooka kuba ennamba y'ebigwa bitalaze (112, 000, 911). Buno bulagirizi bwa bujjanjabi obusooka obwa bulijjo, si kuwabula kwa musawo. Obujjanjabi obusooka obw'omusingi

Weekuume

  • Tokwatako, tokwata wadde okusoomooza ensolo ey'omu nsiko, ne bw'eba ntono, era ne bw'eba erabika nga yeebase oba nga efudde.
  • Gireke n'ebbanga. Bw'osisinkana emu, beera mukkakkamu, dda emabega mpola era gireke egende mu kkubo lyayo.
  • Bw'emu ekuluma: beera mukkakkamu, totambula, kuba ennamba y'ebigwa bitalaze (112, 000, 911) oba tuuka mu ddwaliro mangu. Jjukira bwe yali efaanana, ekifaananyi kiyamba.

Tekikunoonya. Kikozesa obusagwa bwakyo okukwata emmere oba okwekuuma, era kyandisinze kwekweka. Ebirala ku kwekuuma

Ebituufu

1

Its silk is the toughest biological material ever studied. It is over ten times tougher than a similar amount of Kevlar.1

2

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

3

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

4

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

5

Flies that feed on its catches have been found living alongside it, and the spider sometimes chases them away.1
