Nephila inaurata, commonly known as the red-legged golden orb-weaver spider or red-legged nephila, is a species of golden orb-weaver spider. It is native to southern and East Africa, besides several islands of the western Indian Ocean (Madagascar , the Seychelles, Réunion, Mauritius, Rodrigues).

Habits

Like other spiders in the subfamily Nephilinae it can weave webs so strong that sometimes even birds and bats get caught. Its webs can be found in damp places such as large trees and unpolluted areas to which no cars have access; normally several are strung together to form enormous "homes" so as to cover as much surface area as possible.

Prey

This species feeds on flies, mosquitoes, moths, wasps and unfortunate beetles who happen to get tangled up.

Subspecies

In addition to the nominate subspecies (N. i. inaurata) of Mauritius and Réunion, a second subspecies is currently recognized: N. i. madagascariensis (Vinson, 1863), which occurs from South Africa to the Seychelles.

Captive breeding

This species is commonly kept in captivity. Egg sacs the size of a small marble are made of thick silk and contain 100-200 eggs which hatch after two months. They start out with a 2mm leg span and grow rapidly. Males mature in one to two months depending on the form. A small percentage of males mature early and resemble a small, black crab spider with only an 8-10mm leg span. Most males mature later and resemble the form of the female but have very little color and only a 25-30mm leg span. Females mature in four months with an approximate 100mm leg span.
