Some ground beetles are metallic green or blue or are marked with spots of metallic red or gold. This beetle is about 1 inch long and brilliant metallic green. They have three pairs of well-developed legs and run quickly. Adults emerge to mate and disperse. Eggs are laid singly in soil.
Development is usually complete in one year.
Mouthparts are for chewing. Ground beetles are commonly encountered under stones, bark, logs and other debris laying on the ground. When disturbed, they run rapidly. At night they seek prey and some species are attracted to lights. Larvae are also encountered under objects or in burrows in the soil or under bark of trees.
