Carabus problematicus (Herbst, 1786)
Ground Beetles (Carabidae) are quick, long-legged predators, equipped with powerful jaws. is one of the largest species in the UK, measuring about 20-30mm in length. The one pictured was one of two, found in mid-January 2010 under a log on Budby South Forest. It has been much less recorded at Sherwood, than the very similar Carabus violaceus and indeed, this was the first time we have found this species. C. problematicus is perhaps best distinguished by the more structured elytra, with raised areas forming distinct grooves at times.
