Carabid beetle or Ground beetle
Carabidae (Family)
- Order & Family
- Order: Coleoptera, Family: Carabidae
- Size
- Generally 0.1 to 1.4 inches (3 mm to 35 mm) in length, though most common species are 0.4 to 0.8 inches (10-20 mm). The beetle in the image appears to be on the smaller side of this range.
Natural Habitat
Typically found outdoors in soil, under rocks, logs, leaf litter, and other debris. Some species may occasionally wander indoors, particularly during colder weather or prolonged dry spells.
Diet & Feeding
Most ground beetles are predatory, feeding on a wide variety of small invertebrates such as caterpillars, slugs, snails, aphids, and other insect larvae. Some species may also consume seeds or fungi.
Behavior Patterns
Primarily nocturnal, these beetles are fast runners. When disturbed, they may play dead or emit a foul-smelling fluid as a defense mechanism. They undergo complete metamorphosis (egg, larva, pupa, adult).
Risks & Benefits
Benefits: Ground beetles are highly beneficial predators in gardens and agricultural settings, helping to naturally control pest populations. Risks: Generally harmless to humans. They do not bite or sting and are not known to carry diseases. Occasionally, they may enter homes but do not cause structural damage or infest food.
