Crenulatewinged Grasshopper

Cordillacris crenulata (Bruner)

Cordillacris crenulata

Cordillacris crenulata, the crenulatewinged grasshopper, is common in the shortgrass prairie of eastern Wyoming, where it lives in patches of blue grama or buffalo grass. Eggs overwinter in the soil and hatch in late May or early June. Adults are present from early July through August. It feeds on grasses and has a preference for grama grasses. Its small size keeps it from being an economically damaging species, but it may damage rangelands in conjunction with other species.
