Bradynodes obesa, the mountain lubber, is found in the lower
elevations in the Big Horns and Wind River Mountains and may occur in other
suitable areas of northwestern Wyoming. It lives in localized populations
at the transition area between the pine savannah and the sagebrush desert.
Eggs overwinter and hatch very early in the spring. Adults are found in
May and June and are gregarious. Their feeding habits are little known
in Wyoming, but they may prefer grasses. Any damage to rangelands would
be limited by its localized habitat and its occurrence early in the year.
