Feather – legged Spider (Cyrtophora citricola) Has no venom, it quickly wraps its prey in silk and is covered with digestive enzymes. Can overpower much larger and more powerful insects than itself.

Banded – legged Nephila (Nephila senegalensis) Females abodomen can be 25 - 30 mm. The silk used in the web has a golden colour, hence Golden orb - web spiders.

This Funnel web Spider (Agelena australis) was seen on 24/09/2004 on the Spring festival outing to the Zandvlei Nature Reserve. A light shower of rain provided the drops on the web.

This Baboon Spider is in a glass jar for identification. Una Hartley found him in the garden at Westlake Wetlands Lakeside on 20/08/2004 and took it to Rondevlei Nature Reserve for identification. It was returned to the place it was found. He measures about 75 mm across and about 100 mm long. Colour black velvet like body and legs with longer brown hairs on the back of the abdomen. This is a much larger specimen than is usually found locally.
Subsquently a number of Baboon spiders have been seen in variuos locations around Zandvlei in the Spring and Summer 2004.

This Rain Spider (Palystes natalius) was making its nest. 2 leaves were formed and the nest laid on the leaves. She still had to cover the nest with leaves and spin the outer web, which took about 6 hours.
