Grasshoppers of Wyoming and the West


Migratory Grasshopper

Melanoplus sanguinipes (Fabricius)

Melanoplus sanguinipes

Melanoplus sanguinipes, the migratory grasshopper, is common throughout the grasslands of Wyoming. When the population is dense, large swarms can move around the state or into Wyoming from adjacent states. The most recent outbreak of this species was from 1985 to 1987. Eggs overwinter in the soil and hatch in June. Adults can be present from mid July to September. It is a mixed feeder preferring forbs at low population densities, but at high populations it can eat all the available rangeland forage. Control measures are often necessary to protect rangelands but results can vary due to reinfestation by migration.
Ref.: Pfadt 1988, and Capinera and Sechrist 1982.
