Ground Beetles

Order: Coleoptera
Family: Carabidae

Description

There are many species of ground beetles, usually found under debris, in soil cracks or moving quickly along the ground. Most are black or brown and have long legs. Ground beetles are generalist predators with powerful jaws that feed on nearly any insect pest that spends time on the soil surface. Immature stages are distinctly different from adults and more often are found within the top few inches of soil.
