Amphitornus coloradus, the striped grasshopper, is common on the rangelands of Wyoming. Its preferred habitat
is the mixedgrass and shortgrass prairies of eastern Wyoming. There are several different
color forms in Wyoming that can make identification confusing. After overwintering
in the soil, eggs hatch early in the spring. Adults are present from late June to
September. This species feeds on many of the valuable forage grasses in Wyoming and
in conjunction with other grass-feeding grasshoppers, it can cause severe forage losses.
