This ground beetle, like others of its taxonomic group Tribe Cychrini, is incapable of flight due to fused and highly reduced wings. As its name indicates, the tuberculate rare snail-eating beetle preys upon snails, and it has bumps (tubercles, hence 'tuberculate') across its back. It is nocturnal, and it may be found in moist shaded areas of coniferous forests, clearings, and moraine habitats. It has been recorded from BC south to California.
