Males and females work in pairs to dig burrows beneath animal excrement. They move some of the excrement 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.
