Family Dysderidae

Long-fanged six-eyed spiders or cell spiders Home <------


In this family we can find two genera (Dysdera and Harpactea) with both two species in NW-Europe.

These spiders vary in size between 5 and 14 mm and have an elongated body.

Like the Oonopidae, Segestriidae and Scytodidae, they also have six eyes.
It is a sinister looking spider with two enormous fangs.
The spiders spent the day under stones, especially stones that are warmed by the sun, in a silken cell in which the female spider lays her eggs. It is an active runner.
Dysdera crocata is a cosmopolitan in the United States and usually found around buildings.
She is agressive and will defend herself very quickly.
Because her fangs are long and she has strong jaws her bite can prenetrating human skin. This can be painfull like the prick of a needle.
Dysdera has a prey specialisation in woodlice.
