Running Crab Spiders

Philodromidae, also known as philodromid crab spiders and running crab spiders, is a family of araneomorph spiders first described by Tord Tamerlan Teodor Thorell in 1870 (then known as subfamily Philodrominae within Thomisidae). It contains over 500 species in about thirty genera.

The most common genus is Philodromus which is widespread, similar to Ebo. Other common genera include the elongate grass-dwelling Tibellus and the widespread Thanatus, which includes the house crab spider that commonly captures flies on and in buildings.
