The Spiders of Europe and Greenland
Family: Segestriidae (Six-eyed Spiders)
Biology: A small family which sometimes is considered just a subfamily of Dysderidae.
Genus: Segestria Latreille, 1804
Characters of genus: Large six-eyed spiders with elongate abdomen and having the three anterior pairs of legs directed forward. Males and females are alike, but males have a slimmer and smaller abdomen. There are three species in Northern and Central Europe, which all build tubular retreats in cracks of walls, cliffs and trees and under stones. About 10-15 threads radiat from the entrance hole of the retreat and serve as detectors of prey location. Once prey touch a thread the spider will rush out to attack and seize the prey, and then take it back to to the retreat for consumption.
Segestria senoculata castrodunensis Gtaz, 1889
