|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.
