Ground Beetles Carabidae

Ground, Tiger and Wrinkled Bark Beetles
Carabidae

 

Long, flattened and usually without hair. Generally the head is narrower than the thorax, which is again narrower than the wings (except for the Tiger Beetles). Most of them are shiny, reddish-brown to black.

Some are predators on other insects and snails, some eat debris and litter, and some feed on plant material.

All have 11 antenna segments. Feet all have 5 segments, i.e. 5-5-5 tarsal formula.

Many are attracted to lights.
