Epomis beetles are often metallic blue or green colored, with a striking yellow-orange rim on the elytra and mostly yellow-colored legs and antennae. Preliminary reports have detailed an unusual trophic interaction in which, in contrast, larvae of the ground beetle Epomis prey upon juvenile and adult amphibians. Like adult carabid beetles, they have six legs and visible mouthparts. Most ground beetles are shiny, black or brown and iridescent, and are sometimes confused with cockroaches. Ground beetles are very closely related to tiger beetles (family Cicindelidae), and most of the beetles in both of these groups are predators (both as larvae and adults). The three larval instars live in debris or in burrows in the soil. HIVE BEETLE BIOLOGY ^ Hive beetles are largely scavengers that are drawn to honey and pollen. The larvae live below ground, where they use their large pincher-like mandibles to devour soil-dwelling insects.

Many of the nocturnal species are dark black or brown; these are the ones that scurry away for cover when you turn over a dirt clod, rock, or log. 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. Trautner Jürgen, & Geigenmüller Katrin (1987). Beetle larvae eat honey, pollen and young developing bees leaving behind feces that causes honey to ferment. HIVE BEETLE BIOLOGY ^ Hive beetles are largely scavengers that are drawn to honey and pollen. In North America, the ground beetles number well over 2,000.
