Derotmema haydenii
Hayden's grasshopper
Derotmema haydenii is a medium-sized band-winged grasshopper native to western North America. It inhabits disturbed prairie habitats with high percentages of bare ground, including prairie dog towns, roadsides, and vacant lots. The species is notable for its late hatching phenology and distinctive nymphal coloration. Adults are active from late July through September and feed primarily on forbs rather than grasses.
