The male Prowling spider has a striking groove at the end of their palps. The spiders do not build a web and hunt at night. They make a sac-shaped silken retreat, in which they hide during the day and also keep and guard their egg sacs. In Europe about 30 species can be found
Cheiracanthium until recently belonged to the family Clubionidae and thereafter Miturgidae, but is now considered to be part of the new family Eutichuridae. They have long, slender legs, with pair of legs I clearly longer than the rest. Generally they are also pretty big. They hunt at night and hide themselves during daytime in a silken retreat under stones or vegetation.
