Melanoplus borealis, the northern (spurthroated) grasshopper,
is confined to the higher forested areas and to areas above timberline
in Wyoming. It prefers moist alpine areas and marshy meadows. In recent
years it has been especially common in the Big Horn Mountains. Eggs overwinter
in the soil and may require two years to hatch. Adults are present in August
and September. This species is a mixed feeder that has a distinct preference
for lupine. It may aid in controlling abundance of this poisonous plant.
