Spitting Spider - Scytodes thoracica


This fascinating species is the sole member of its family in Britain. It ranges from 3-6mm in size and the cephalothorax is massively domed when viewed from the side - a distinctive feature. The cephalothorax and abdomen are similar in size, colour and markings, both being straw-coloured and marked with black flecks. The legs are also straw-coloured with dark annulations.

Identification difficulty

Found in buildings, usually heated ones, and it has a particular association with museums.

When to see it

All year.

Life History

It is a slow-moving, nocturnal hunter which catches its prey by the unusual technique of squirting a sticky, venomous fluid from its chelicerae. These are moved in a side-to-side motion resulting in a zig-zag of threads that pins its prey to the surface. The same mechanism is used as a defense against other spiders.

UK Status

Widespread in southern Britain.
