Hersilia GERGASSI
 
The oval abdomen is wider posteriorly with the posterior lateral spinnerets extending out parallel to each other.

They are cryptically coloured in variegated shades of cream, orange, green, brown, grey and black.

They are quick and difficult to capture as they disappear into the narrowest of crevices.


 
Long-spinnered bark spiders

The Hersiliidae is a family of spiders noted for their elongated posterior lateral spinnerets which can be as long as the abdomen.

Photo Left : Distinctive elongate lateral spinnerets used in prey capture by swaying them over the victim thus wrapping the victim in silk.

The inner edge of these spinnerets is lined with silk-producing tubules (spine-like spigots).
 

Hersilia is found in trees.
