Description: The Ground Beetle is a member of the family Carabidae. This large beetle family has over 3,000 species in North America. They are found under logs, rocks, and leaves in moist areas. These beetles measure 1/8-1 3/8" (3-36 mm) long. Many are shiny black, but some are brightly colored. They have a conspicuous prothorax, narrow head, and long legs with spurs on the tibiae. The threadlike antennae arise from between large compound eyes. Most ground beetles rapidly pursue prey at night. A few eat pollen, berries, and seeds. Some species lay eggs in cells made of mud, twigs, and leaves. The larvae are predators, and take 1 year to grow from eggs to adults. Adults usually live 2-3 years, or rarely 4 years.
