Parawixia

Parawixia is a genus of orb-weaver spiders first described by F. O. Pickard-Cambridge in 1904.[2] Most species are found in the Neotropics but one species, Parawixia dehaani, is found in Australasia and tropical Asia as far west as India.[1]

Natural history

Parawixia audax, one of the better known species, makes a large loose web, placing itself either in the center with its head down or in a retreat created from a rolled-leaf. This species builds webs 1 to 2 metres (3 ft 3 in to 6 ft 7 in) above the ground, but there are likely many more species farther up in the canopy that are rarely collected by usual means.

Parawixia bistriata builds its webs much higher from the ground, frequently found on telephone poles. It is known to be social, and all individuals in a colony are of the same age and size. During the day, they share a retreat where they cluster together.[3]
