Histeridae is a family of beetles, with fifty genera occurring in Britain. The members have a hard body, geniculate antennae with a thick, button-like club, the elytra leaves the last two abdominal tergites exposed, they are able to retract their head underneath the pronotum, and both the larvae and the adults hunt the larvae of other insects in decaying plant and animal matter. They are chiefly found in carrion, dung, rotting fungi and under bark. Research Histeridae
