The Trogidae or hide beetles are a family of beetles with a distinctive warty or bumpy appearance. Found worldwide, the family includes about 300 species contained in three or four genera. Trogids range in length from 2.5 to 20.0 mm. Their shape is oblong to oval, with a generally flat abdomen. Their color ranges from brown to gray or black, and they often encrust their bodies with soil. They resemble scarab beetles with heavy limbs and spurs.
