Stethophyma gracile is restricted to moist forested meadows in
Wyoming. In addition to our record from Crook County, this species has
been reported from Yellowstone National Park. It is assumed that eggs overwinter
in the soil. Our collection on July 18, 1991, is composed of mature nymphs
and adults. Its feeding habits in Wyoming are not known. Because of limited
suitable habitat and scarcity, it is not a pest in this state.
