The Ground Beetles, otherwise known as Carabidae, are a large family of beetles characterised by their way of living. Ground Beetles will either be soil or ground dwellers, and they're incredibly diverse in their looks and ecology. The wingcases, come in many sizes, shapes, colours and textures; however, are generally ovular and dull in appearance, although some species show some form of iridescence. They're considered beneficial insects for the garden as most are polyphagous, meaning they have flexible feeding habits. For example, the violet ground beetle (Carabus violaceus) is a reasonably large beetle spanning roughly 2.5cm in length. An adult will eat a variety of things, including slugs, leatherjackets, cutworms and caterpillars! Some species take a different approach and are specialist predators, eating only one type of food.

Traits

These beetles are predatory insects that will hunt the pests in your garden.
These insects are a resource for other wildlife and can provide beneficial ecosystem services.

Appearance

This family of beetles is hugely diverse. They can span anywhere between 2-30mm. Most are black to brown but can come in a variety of tones, such as blues and greens with an iridescent shine. Beetles belonging to the Notiophilus genera possess black wingcases (elytra) involving some form of metallic bronze patterning. Getting a little closer to these beetles, you may notice the wingcases are indented with rows of tiny spots. These are sensory cells which enable beetles to sense the surrounding environment, some may be used as scent glands, or to detect nearby movement. They generally possess long legs and powerful jaws. These adaptations help them to chase and subdue their prey.
