Chlaenius croesus is a species of ground beetle in the family Carabidae, found in Africa. It is a member of the subgenus Epomis, the larvae of which are notable for being obligate role-reversal predators. Amphibians such as frogs are normally predators of beetles; however, Epomis larvae feed exclusively on amphibians.
