Epomis nigricans

Epomis nigricans is a species of ground beetle native to the Palearctic. It is known from China, Japan, North Korea, and South Korea.

Adult beetles are metallic copper-green colored, with a striking yellow-orange rim on the elytra and mostly yellow-colored legs and antennae. They are 19.5-22 millimeters in length.

The larvae reach a body length of up to 20 millimeters, they are yellow colored with black markings. Like many ground beetle larvae they are elongated with two extensions (Urogomphi) at the rear end. They have characteristic double-hooked mandibles. The larvae feed exclusively on amphibians, which they lure

by making prey-like movements. The adult beetles are generalist predators, but can also feed on amphibians much larger than themselves.
