S Stuthridge From the size you mention, your Rove beetle may be the Devil's Coachhorse beetle, Ocypus olens. But it can only be positively identified by looking under a microscope. According to one website Ocypus winkleri is the most common in the UK and therefore may be your beetle. The Devil's coachorse beetle is a predator, hunting mostly at night, feeding on invertebrates including worms and woodlice, as well as carrion. Rove beetles in general have short elytra (hard wing covers) that cover fully functioning wings so they are proficient fliers. The wing folding process after flight is interesting to watch, if you get the chance. They live in cool damp places at ground level - usually in the garden or woodland habitats, hiding under fallen wood or stones by day and feeding on small insects and grubs. Most of the rove beetles adopt a 'scorpion like' posture when alarmed. They stand their ground, raise the rear abdomen up and open their jaws in a threatening posture. If bothered enough, they will bite - which is usually enough for most of us to 'back off' although the bit will be only superficial.
