Cordillacris occipitalis, the spottedwinged grasshopper, is common
throughout the shortgrass prairie in Wyoming. Populations decrease in the
southwest desert areas and in the mixedgrass prairie. Eggs overwinter in
the soil and hatch in late spring. Adults are present from late June to
August. It feeds on many species of grass but may prefer grama grasses.
This small grasshopper damages rangelands only if populations are very
high or in conjunction with other grass-feeding species.
