Camel cricket (Ceuthophilus sp.) is a very common genus of native crickets. It can be found under rotten logs, under stones, in mole hills, and other moist dark places, but is most often encountered in basements. Unlike most crickets it has no hearing organs (tympanum).

The family (Rhaphidophoridae) is identified by its distinctive, hump-backed shape, lack of wings and tympanum, and antennae longer than the body. The genus (Ceuthophilus) is identified by four end segments (tarsi) on each leg and the lack of a spine on the front of the tibia of the foreleg.
