Size-recessive reversal
Amphibians often prey on beetle larvae. However, the ground beetle Epomis’s larvae reverse this and prey exclusively on the amphibians that are trying to consume them. Two species of Epomis (E. circumscriptus and E. dejeani) use the amphibian’s predation behavior to their advantage by luring the amphibian to them. “The Epomis larva combines a sit-and-wait strategy with unique movements of its antennae and mandibles to draw the attention of the amphibian to the presence of a potential prey.” Out of 400 tests, the larvae avoided the amphibian’s tongue, and counterattacks by attaching itself to the body of the amphibian with an approximate 98% success rate. Once attached, the Epomis larvae begin to feed.
