Paropomala wyomingensis, the Wyoming toothpick grasshopper, is a common grasshopper in the shortgrass prairies
of eastern Wyoming. Its populations diminish in the mixedgrass prairie of the northeast
and in the deserts of the southwest. The eggs overwinter in the soil. Adults are present
from mid July to early September. It feeds on many species of grass including western
wheatgrass, grama grasses, and needle and thread grass. It is rarely abundant but
could damage rangeland forage in conjunction with other species.
