Grasshoppers of Wyoming and the West
Entomology
Fourspotted Grasshopper
Phlibostroma quadrimaculatum (Thomas)
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.
