Grasshoppers of Wyoming and the West
Entomology
Redwinged Grasshopper
Arphia pseudonietana (Thomas)
Arphia pseudonietana, the redwinged grasshopper, is found throughout Wyoming rangelands and prefers areas
with patches of barren ground. Eggs overwinter in the soil and hatch in late June.
Adults occur in August and September. It is a mixed feeder but prefers grasses. It
is never numerous enough to damage rangeland forage except in conjunction with other
species.
