Ground beetles are very common "outdoor" insects that occasionally become pests by wandering into houses and buildings by mistake. This description can only be used for species that live in the soil. [9] The amphibian loses its ability to move and is eaten by the beetle. This makes feeding them really easy: you need to supply them with leaf litter and rotting wood. The heads bear sickle-shaped jaws (mandibles) that are pointed forward. [4], Epomis larvae hunt in a rare reversal of the usual predator-prey relationship between amphibians and insects. The ground beetle family, Carabidae, is one of the largest groups of beetles, with over 1700 species in the United States and several hundred species in Kentucky. Ground beetle larvae have specialized pincher like mouthparts, six legs, and are black, brown, cream, or tan in color.

Ground beetles develop and mature by undergoing complete metamorphosis from egg to adult. Most species of Ground Beetle are carnivorous, and some will run swiftly to catch their prey. Ground beetle larvae look somewhat like garden centipedes with long black or brown segmented bodies. Adults eat caterpillars and other insects, so look for them in areas where insects hide or congregate like under logs, stones, and leaf litter. Tiger beetles are voracious predators that eat many other insects and invertebrates that cross their paths. Adults eat caterpillars and other insects, so look for them in areas where insects hide or congregate like under logs, stones, and leaf litter. However, if they are creating a nuisance, move or remove hiding places next to the house such as log piles, mulch, and debris around the perimeter. Most hide during the day and feed at night. 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. The larvae live below ground, where they use their large pincher-like mandibles to devour soil-dwelling insects. Predation on anurans by, Toshiaki, H. (2006). If beetles are creating a nuisance by flying to lights at night, repositioning the lighting or changing white lights to yellow may reduce the attraction.

Carabid adults and larvae feed on soil dwelling insect larvae and pupae, other invertebrates such as snails and slugs, and sometimes on seeds and organic litter. 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. Ground beetles make up one of the largest groups of beetles in North America, with more than 2600 species. They have characteristic double-hooked mandibles. Beetle Defence during metamorphosis.

These eggs eventually hatch into grubs and the cycle begins again. It is believed to be a major factor in suppression of several lepidopterous pests, e.g., velvetbean caterpillar, Anticarsia gemmatalisHübner, on soybeans. They come out at night to feed o unsuspecting insects. 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. Females typically produce one generation of offspring each year and lay their eggs individually in the soil. These eggs eventually hatch into grubs and the cycle begins again. Biology. Beetles found indoors may be swept up and discarded. Eggs are laid in moist soil.
