Entomology
Crackling Forest Grasshopper
Trimerotropis suffusa Scudder
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.
