Geotrupidae

Geotrupidae (from Greek γῆ (gē), earth, and τρῡπητής (trȳpētēs), borer) is a family of beetles in the order Coleoptera. They are commonly called earth-boring dung beetles or dor beetles. Most excavate burrows in which to lay their eggs. They are typically detritivores, provisioning their nests with leaf litter (often moldy), but are occasionally coprophagous, similar to dung beetles. The eggs are laid in or upon the provision mass and buried, and the developing larvae feed upon the provisions. The burrows of some species can exceed 2 metres in depth.

A few species communicate by stridulation (rubbing body parts together to make sounds).
