Norman Larsen - (Associate Arachnologist, Iziko, South African Natural History Museum) kindly supplied and corrected some of the identifications and information on this page in December 2010.
Comb-footed spiders (Theridion delicatum) Has a round abodmen and slender legs. They can be a variety of colours.
Underside Right way up. Orange Lungless Spider (Diploglena capensis) This spcies has only 2 eyes. They are fast moving nocturnal hunters. They hide in silken retreats under bark and leaf litter, also under rocks. Abdomen is grey and has short silky hair.
Lynx spider (Oxyopidae Peucetia) Between 10 - 23mm leap to catch their prey, they have well developed vision. They do not build webs. They can change colour slowly to blend with the vegetation.
Black - legged Nephila (Nephilidae: Nephila fenestrata) 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. corrected by Norman Larsen.
Common Banded Argiope (Araneidae: Argiope australis) Females abodomen can be 25 - 30 mm in diameter. The silk used in the web has a golden colour, hence Golden orb - web spiders. This spider is diurnal and constructs a zigzag stabilimentum in its web. corrected by Norman Larsen.
Huntsman (Sparassidae: Unidentified Genus)
African Mask
Crab Spider (Thomisdae Synema
Jumping Spider (Salticidae) They are small, less than 5mm and are interesting. They have large eyes as they visually hunt their prey, by pouncing on the victim. They also have a complicated semaphore signalling system with their front legs and pedipalps. corrected by Norman Larsen.

legs are black on the underside with white bands on the underside.
A Bark
Spider (Araneidae: Caerostris sexcuspidata) when on a branch, is very difficult to see even when viewed
from closeup. They blend into the colour of the branch or
twig.

Tropical Tent-web Spider (Araneidae: Cyrtophora citricola) spiderlings in the web. There are sparkling rain drops on the web. corrected by Norman Larsen.
Sheet-web Pisaurids (Pisauridae: Euprosthenopsis
pulchella) They catch prey that lands on their sheet-web through detection and speed. Belongs to same family as Fishing Spiders.
Sheet-web Pisaurids (Pisauridae: Euprosthenopsis pulchella) they catch prey that lands on their sheet-web through detection and speed. Belongs to same family as Fishing Spiders andwas 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. corrected by Norman Larsen.
This Black Common Baboon Spider (Theraphosidae: Harpactira atra) 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.
A Spider Hunting Wasp (Tachypompilus ignitus) with an immobalised Black Common Baboon Spider (Theraphosidae: Harpactira atra). It is dragging the spider away to lay an egg on it so that the larvae can feed on the spider. These wasps also prey on Rain Spiders. corrected by Norman Larsen.
This Cape Rain Spider (Sparassidae: Palystes castaneus) was making its nest. 2 leaves were formed and the nest spun on the leaves. She still had to cover the nest with leaves and spin the outer web, which took about 6 hours. corrected by Norman Larsen.
Cape Rain Spider (Sparassidae: Palystes castaneus) A female guarding her nest. Young spiderlings leaving the nest to begin their life cycle. corrected by Norman Larsen.
