Your letter to the bugman:  Hi! We found this guy on a camping trip at Ponderosa State Park. I’ve been trying to find similar images online but am having trouble. He is very friendly and seems to be flightless.

Dear Ashley & Ben,
Your Hump-Winged Cricket or Great Grig,
Cyphoderris monstrosa, which we identified on BugGuide is actually more closely related to Katydids and it is not a true Cricket.  The BugGuide description is:  “male dark gray dorsally, pale whitish ventrally, with short wings humped up and wrinkled like a loosely-folded blanked heaped on the insect’s back; male subgenital plate with a ventrally-directed process shaped like the nail-pulling claw of a hammer.  female either lacks wings or has them reduced to small stubs.”  Your individual is a male.

Great Grig and Ben
