Eupnigodes megacephala
Big-headed grasshopper
Eupnigodes megacephala is a medium-sized grasshopper widely distributed across western North America. Formerly classified as Aulocara elliotti, this species is notable for its disproportionately large, rounded head and bright blue hind tibiae. It inhabits shortgrass prairies, desert grasslands, and occasionally montane areas up to 8,500 feet elevation. The species is economically significant as a rangeland pest, capable of reaching outbreak densities that severely reduce forage for livestock and promote soil erosion.
