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

Hello arano
Builds its web directly above rivers or the water of lakes, a habitat no other spider is known to use. Its webs are large enough to be noticed from a distance.1

Catches insects, including mayflies, that fly over the water and become caught in its web. One web has been seen holding up to 32 mayflies at a time.1

No anndirte ngal

  • 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

Ina heewi waylondireede e: 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

Humpito

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
