AB: The genus Tetanocera consists of 29 species in North America. The genus is unusual in that its larvae occupy five of the 17 feeding groups recognized in the family, as most other genera of the family occupy only one or two trophic guilds. Seven species have larvae that attack pulmonate aquatic snails, three species attack pulmonate snails stranded on shorelines, four species attack amber snails of the family Succineidae, three species attack slugs, and two species are predators of terrestrial snails. The larval feeding behavior of representative species of each of the five trophic guilds will be described and illustrated.
