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.
