C. L. Koch, 1843
Usually somewhat larger than
and appearing more greyish due to the much denser hairs. A central light band divedes the lobes on the abdomen in two halves.
Female 10-13 mm; male 9-11 mm.
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.
Simon, 1893 (Six-eyed Spiders).
