RECOGNITION
Description
Wingless. Antennae long. Front of pronotum is wide, antennae widely separated at base, head is very large. Tibiae are robust with spines for digging, and tarsi have pads beneath. Hind femora do not extend beyond tip of abdomen in this family. This description applies to the whole family, but this is the most widespread genus in our North America.
Body Length
21-69 mm.
Diversity
The family Stenopelmatidae is being revised by David B. Weissmann. 14 species are currently described in the family, but there may be as many as 60 North American species, most presumably in this genus. Family is under revision by David B. Weissmann. The other North American genus in this family, Ammopelmatus, has, apparently, only two rare and local representatives.

BIOLOGY
Live in burrows and under rocks, logs, may wander on surface at night. Adults, and sometimes nymphs, strike ground with abdomen to produce species-specific drumming patterns (1). Female makes depression in soil for masses of oval, white eggs. Female often devours mate. One generation per year.
Food
Predatory on other insects, also feeds on roots, decaying vegetation. Sometimes found eating potatoes.
Habitat
Varied, under rocks, logs, and some appearing in sand dunes.
Importance
Said to be able to deliver a strong bite, but also to make a good pet.
Distribution
Western United States, basically west of 100 west longitude - just reaching western Dakotas, Nebraska, Kansas, Oklahoma, Texas.
