This is a spectacular grasshopper species, not hard to find in the Texas Panhandle - Great Crested Grasshopper a.k.a. Dinosaur Grasshopper, Tropidolophus formosus. This one was on snakeweed in early fall 2009 at Wildcat Bluff Nature Center. Although most grasshoppers are generalists when it comes to diet, this species actually specializes on plants in the Malvaceae family (such as scarlet globe mallow and wine cup). Males of this species have noisy displays both in flight (crepitation) and on the ground (stridulation).
