Carabid beetles are considered to be mostly opportunistic feeders that consume a variety of foods; however, the majority of species have been observed as primarily predatory, feeding on other insects and related organisms. Most species locate food by random search, although some day-active (diurnal) species hunt by sight.

Adults can live between one and four years. Larger species, as well as those that over-winter as larvae, tend to have the longest life spans (Lovei and Sunderland 1996). While many ground beetle species have functional wings, flight is used primarily for dispersal, such that they spend nearly their entire lives on the ground.
