Trachyrhachys kiowa, the Kiowa grasshopper, is a very common
grasshopper throughout the rangelands of Wyoming. It becomes most abundant
in the shortgrss prairies and least abundant in the desert southwest. Eggs
overwinter in the soil and hatch in June. Adults are common from mid July
to September. It feeds on grasses and has a distinct preference for blue
grama where available. At times large populations will damage rangeland
forage, usually in conjunction with other species.
