Ground Beetle
Carabidae (family)
- Order & Family
- Order: Coleoptera, Family: Carabidae
- Size
- Typically 3 mm to 35 mm (0.1 to 1.4 inches), depending on the species.
Natural Habitat
Highly diverse habitats including forests, grasslands, agricultural fields, gardens, and even urban areas. They are typically found under logs, stones, leaf litter, mulch, or burrowed in the soil during the day.
Diet & Feeding
Mostly carnivorous, preying on a wide variety of small invertebrates such as caterpillars, slugs, snails, other insect larvae, and sometimes even smaller insects. Some species may also consume seeds or fungi.
Behavior Patterns
Ground beetles are primarily nocturnal predators, although some species are active during the day. They are fast runners and can quickly pursue their prey. When disturbed, some species may emit foul-smelling secretions from glands at the rear of their bodies as a defense mechanism. They undergo complete metamorphosis with egg, larval, pupal, and adult stages.
Risks & Benefits
Ground beetles are largely beneficial insects, especially in agricultural and garden settings, as they help control populations of many pest insects and slugs, reducing the need for chemical pesticides. They pose no significant risk to humans, although some larger species may deliver a pinch if handled. Their defensive secretions are generally harmless to humans.
