… a North American dung beetle, with a range from the eastern US to the Rocky Mountains. Males have a black horn which curves backward toward the thorax. Length is about 2-3 cm. Males and females work in pairs to dig burrows beneath animal excrement, usually that of mammals. They move some of the extrement down into the tunnel, where the female lays her eggs in it. The grubs feed on the excrement for several instars until pupating. This species, like all dung beetles, are not pests, and play an important role in reducing fecal matter in the environment, thus reducing the number of disease spreading flies.
