Grasshoppers of Wyoming and the West


Bigheaded Grasshopper

Aulocara elliotti (Thomas)

Aulocara elliotti

Aulocara elliotti, the bigheaded grasshopper, is common throughout the rangelands of Wyoming but is less numerous in the desert portions of the southwest. Several different color patterns occur for this species in Wyoming. Specimens from the southwest have shorter wings and may be confused with A. femoratum. Eggs overwinter in the soil and hatch early in the spring. Adults can occur from mid June to September. This grasshopper feeds on many species of grasses and may be the most damaging species to grasses in Wyoming. Control measures are often necessary to protect forage.
