Spharagemon bolli, a common grasshopper in Nebraska, is occasionally
collected in the Black Hills of Wyoming and other areas in extreme eastern
Wyoming. It prefers sunny forest openings with dry grasses. Eggs overwinter
in the soil. Nymphs become adults in late July or early August. It is primarily
a grass feeder but it is not considered a pest species in Wyoming.
