Rhaphidophoridae
The orthopteran family Rhaphidophoridae of the suborder Ensifera has a worldwide distribution.Common names for these insects include the cave weta, cave crickets, camelback crickets, camel crickets, spider crickets (sometimes shortened to "criders", or "land shrimp" or "sprickets") and sand treaders. Most are found in forest environments or within caves, animal burrows, cellars, under stones, in wood or in similar environments.All species are flightless and nocturnal, usually with long antennae and legs. There are more than 1100 species of Rhaphidophoridae described. The well-known field crickets are from a different superfamily (Grylloidea) and only look vaguely similar, while members of the family Tettigoniidae may look superficially similar in body form.
Most cave crickets have very large hind legs with "drumstick-shaped" femora and equally long, thin tibiae, and long, slender antennae. The antennae arise closely and next to each other on the head. They are brownish in color and rather humpbacked in appearance, always wingless, and up to 5 centimetres (2.0 in) long in body and 10 centimetres (3.9 in) for the legs. The bodies of early instars may appear translucent.
