The ground beetles are a large group of predatory insects in the family Carabidae. Adults and larvae are considered beneficial and will eat almost any type of insect, including: caterpillars, root maggots, snails and other soil dwelling insects. There are more than 3,000 different kinds of ground beetles in North America and they range from 6-30 mm in length. Many will have a solid, shiny black body with hardened and ridged forewings . Some ground beetles have a black body and iridescent red, purple or green markings on the forewings. Most ground beetles have a relatively long body, flattened head, threadlike antennae, and long legs. Sometimes adults can have enlarged mandibles for grasping prey. As the name suggests, adults prefer to run on the ground and rarely fly. In general, adults are actively hunting on the ground at night and hide under rocks or debris during the day.
