Grasshoppers of Wyoming and the West

Entomology

Fourspotted Grasshopper

Phlibostroma quadrimaculatum (Thomas)

Phlibostroma quadrimaculatum

Phlibostroma quadrimaculatum, or "P-quad," is common throughout the grasslands of eastern Wyoming. It does not occur west of the Continental Divide in Wyoming. It becomes most numerous in the shortgrass prairies. The eggs overwinter in the soil. Adults are common from mid July to late August. This species is primarily a grass feeder and prefers blue grama. At times it becomes abundant and control programs are necessary to prevent damage to rangeland forage.
