Segestriidae (Tube-Dwelling Spiders)

As well as the Dysderidae, the Segestriidae have six eyes. They have a small cigar-shaped abdomen and some species have markings in a clear spotted pattern. They build a funnel-shaped silken tubular retreat under tree bark or inside wall cracks. In Europe 17 species occur, in two genera.

Genus Segestria

The spider sits and waits close to the exit of its funnelweb, its two front legs facing forward, until a prey touches the signal wires. The spider will then pull it inside. The female lays her eggs deep in her silken tube and after hatching, she remains with her offspring until they spread.
