The genus Scarabaeus consists of a number of Old World dung beetle species, including the "sacred scarab beetle", Scarabaeus sacer. These beetles feed exclusively on dung, which they accomplish by rolling a piece of dung some distance from where it was deposited, and burying it in order to feed on it underground. They also prepare food for their larvae by excavating an underground chamber, and filling it with balls that have eggs laid in them. The growing larva feeds upon the dung ball, pupates, and eventually emerges as an adult.
