Circotettix carlinianus, the snapper grasshopper, is a noisy grasshopper with dark or black hindwings. It
occurs throughout Wyoming's grasslands and prefers dry areas of bare ground or eroded
soil. It is more often heard than seen. Eggs overwinter in the soil and hatch in late
May or June. Adults are present from mid July to September. It is thought to be a
mixed feeder on forbs and grasses, but is never abundant enough to damage rangelands.
