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.
