Way of life

The adults hunt, unusual for carrion beetles, on the vegetation for caterpillars , the larvae of plant wasps and aphids . The females lay their eggs one by one in the ground. The larvae that hatch are black and a maximum of 20 millimeters long. They also feed predatory on insect larvae living in the ground and also on carrion . Pupation takes place in the same year, the new generation of beetles overwinters in the ground and will appear next April.
