Grasshoppers of Wyoming and the West
Entomology
Spottedwinged Grasshopper
Cordillacris occipitalis (Thomas)
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.
