Velvet Spider (Eresidae)


This black Velvet Spider had lived in the bark of an old log in my previous garden in Gauteng for approximately 2 years and she let me coax her out for a photographic session every now and then. These spiders are robust and deliberate in the way that they walk and she even allows me to gently stroke her abdomen and thorax, which is covered in thick, smooth, velvety hairs.


The velvet spiders (family Eresidae) are a small group (about 100 species in 10 genera) of almost totally Old World spiders (exception: a few species are known from Brazil). The most commonly seen genera are Gandanameno and Dresserus to which the common name velvet spider applies more specifically.



Velvet spiders are found under rocks or bark resting in a sheet of dense white silk and are often confused with baboon spiders. They can live up to 5 years. Free living but rarely leave the safety of their webs. Even though these spiders can be large in size (up to 18mm) they very rarely bite. Not much is known about the affects of their venom. It is highly unlikely that this spider’s venom is of importance to humans.
