Members of this genus have very long and narrow heads to allow them to feed deep within a snail shell. The beetle in the photo above seemed to be considering a Myriapod meal instead. The beetle had a purple sheen the camera failed to capture.
The genus Scaphinotus is notable for the very narrow manibles and for the numerous striations on the elytrafourteen to eighteen on each elytron.
