Derotmema haydeni, the Hayden grasshopper, is found in the shortgrass prairies and desert areas of
Wyoming. Populations diminish northeastward in the mixedgrass prairie. It prefers
areas with patches of barren soil where its coloration blends with the soil. Eggs
overwinter in the soil and hatch in early June. Adults are present from mid July to
September. This species is a mixed feeder of many species of forbs and grasses.
