Image of Mestobregma impexum Rehn & J. A. G. 1919

Description:

"About half a dozen of these grasshoppers were found at a gravelly pullout off Highway 4 at nearly 6,800 ft elevation. They were identified by their general coloration, large heads, blue hind tibiae with a pale proximal band, and (not visible in these pictures but seen in while stopping here), their yellow hind wings with black bands around their outer rims. They made a ""cracking"" sound when they flew."
