Ground beetle larvae can be found in soil, grass, and under bark or debris. Tiger beetle larvae live in vertical burrows in dry or sandy soil such as found in paths or beaches. Both families include important enemies of many turf pests such as armyworms, cutworms, grubs, snails, and slugs. Some species of ground beetles have been known to eat seeds and thus do occasional damage. However, economic damage by ground beetles in the Southeast is negligible.
Most ground beetles complete a life cycle within a year.
Ground beetles overwinter as larvae or adults. Eggs are deposited singly in the soil. Larvae develop in or on the soil, especially under stones, boards or other debris. Pupation takes place in the soil. Adults are usually nocturnal, and may be attracted to lights.
