Grasshoppers of Wyoming and the West


Brownspotted Grasshopper

Psoloessa delicatula (Scudder)

Psoloessa delicatula

Psoloessa delicatula, the brownspotted grasshopper, is common throughout the rangelands of Wyoming. It prefers grasslands with areas of barren soil. Eggs are laid in the soil in late May and June. Hatching starts in mid July, and nymphs overwinter. Adults can be found from late April to August but are most common in May and June. This grasshopper feeds on grasses. It can be numerous enough to damage grasses, but damage is usually not serious because of its early-season occurrence and small size.
Ref: Pfadt 1991, Otte 1981, and Capinera and Sechrist 1982.
