Bark Spider – Caerostris sexcuspidata

Bark Spider

I am not going to say too much about this spider as I have given a pretty good explanation of it on a post a few weeks ago. You can find the information here.

I was trying out a flash guide that I made from one I saw somewhere on the internet. These are the resultant pics of this spider with this flash guide.

Here is a macro of its ‘face’. A stunning looking spider, close up.

South African Bark Spider

Bark Spiders are orb-web spiders. They construct webs up to 1.5 meters in size stretching from tree to tree. They are very well camouflaged spiders mimicking the colour and shapes of bark brilliantly. Bark Spiders are nocturnal. This shot was take just before the sun was about to set.
There are four species report from southern Africa namely: Caerostris corticosa, Caerostris mitralis, Caerostris sexcuspidata and Caerostris vinsonii.

Caerostris corticosa:
Caerostris corticosa occurs away from forest and appears to be an arid to fynbos species found in Botswana, the Northern and Western Cape with a record for Pretoria. At Grootvadersbos Nature reserve it was found to be common in burnt fynbos with webs spread between dead branches about 1.5-2metres above the ground. No spiders were found in the adjacent forest some 100-200metres away. It was not as common in unburnt fynbos. The egg sacs has a yellowish tinge and the spiderlings are black. The adult females were all a dark grey and no males are known.

Caerostris mitralis:
Caerostris mitralis is found in Mozambique and Kwazulu/Natal in South Africa.

Caerostris sexcuspidata:
Caerostris sexcuspidata, although nocturnal, can be found on her web in shaded forested areas during the day. This is the most widespread species occurring south of the 5° North (central and east Africa) It is the common species in South Africa and the species with the most variations in abdomen shape.

Caerostris vinsonii:
Caerostris vinsonii occurs from central Africa to Botswana, Mozambique and Kwazulu/Natal in South Africa.

Wall Crab Spider

Wall Crab Spiders, from the family Selenopidae, are common in houses, especially in the eastern regions of South Africa. These are pretty common house spiders and are also known as Flatties. They have flat bodies and legs that are spread out like a crab. They have long spines on the legs possibly for sensing movement. They are extremely agile and can move very fast when either hunting or if they are disturbed.
