Ground beetle adults are flat, black or brown, long-legged and swift-running insects. Sometimes the colors are brilliant metallic greens, blues or purples, occasionally spotted with iridescent dots or pits of gold. The adults range in length from 1/2 to 1 1/2 inches. Ground beetle larvae are dark-colored, slender, a little flat and slightly tapering to the tail, which terminates in two bristly, hair-like or spine-like structures. Both the adults and larvae feed on small, soft-bodied insects, eggs and worms. Ground beetle adults and larvae are generally found on the soil, acting as ground level predators.
