Appearance
This species is commonly kept in captivity. Egg sacks 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 legspan 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 legspan. Most males mature later and resemble the form of the female but have very little color and only a 25-30mm legspan. Mature males are rarely, if ever, observed feeding. Females mature in four months with an approximate 100mm legspan.
Naming
In addition to the nominate (Nephila i. inaurata), a second subspecies is currently recognized: Nephila inaurata madagascariensis (Vinson, 1863), which occurs from South Africa to the Seychelles.
Food
This species feeds on flies, mosquitoes, moths, wasps and unfortunate beetles who happen to get tangled up.References:
