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.
