Grasshoppers of Wyoming and the West

Entomology

Striped Grasshopper

Amphitornus coloradus (Thomas)

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.
