RECOGNITION
Description
The Carabidae have a variety of body shapes and coloring. Most are shiny black or metallic with ridged elytra. In some species the elytra are fused rendering the beetles incapable of flight. In California, all but the Flanged Bombardier Beetles (Paussinae) have a groove on the foretibiae bearing a comb of hairs used for cleaning antennae.
Body Length
0.7-66 mm.
Diversity
By far the largest family of Adephaga and one of the largest insect families, with about 2,440 species (including 64 non-native species) in almost 200 genera (15 subfamilies, 50 tribes) in America north of Mexico, and about 34,000 species in 23 subfamilies an 110 tribes worldwide.
Similar Taxa
Darkling Beetles (Tenebrionidae) have overlapping habitats and are encountered as frequently.

BIOLOGY
Food
Most adults rapidly pursue their prey (other insects) at night. A few eat pollen, berries, and seeds. Most larvae are predators, but some are herbivores or parasitoids.
Habitat
All terrestrial habitats. Common habitats are under the bark of trees, under logs, or among rocks or sand by the edge of ponds and rivers.
Importance
As predators of invertebrates, including many pests, most ground beetles are considered beneficial organisms.
Distribution
Worldwide.
