Trimerotropis suffusa, the cracklingforest grasshopper, is common
at moderate elevations in the mountains of Wyoming. It prefers small forest
opening or areas along mountain roads. It is apparently absent from the
Black Hills. Eggs overwinter in the soil. Adults are most common in August
and early September. This grasshopper is a mixed feeder and is known to
feed on lupine, yarrows, and fescues. Although often present in preferred
habitat it is rarely numerous. Its effects on forage and weeds are unknown.
