Epomis
''Epomis'' is a genus of beetle. The larvae of this genus are notable for being obligate role reversal predators. Amphibians such as frogs are normally predators of beetles, however ''Epomis'' larvae feed exclusively on frogs and other would-be predators. ''Epomis'' larvae have been observed to lure predators by making prey-like movements, then evade the predator's attack and disable the predator, often with a bite to the throat or underside, otherwise with a paralysing incision to the back. It is theorised that adult ''Epomis'' beetles may also feed on predator species. Scientists speculate that ''Epomis'' evolved this behavior as an aggressive evasion tactic in response to predation by amphibians and the success of this tactic led to ''Epomis'' becoming an obligate predator itself. ==References==
