Rivers' snail-eating beetle
Scaphinotus riversi, commonly known as Rivers' snail-eating beetle, is a flightless ground beetle in the family Carabidae. The species is endemic to California, where it inhabits forested environments. Adults are brachypterous (short-winged) and exhibit nocturnal activity patterns. As a member of the genus Scaphinotus, it is presumed to be a molluscivore, feeding on snails and slugs, though direct dietary observations for this specific species are not documented.
