HOSTS/PREY OF LARVAE: During laboratory rearings in New York, U.S.A., larvae killed and developed on seven species of North American freshwater pulmonate snails of six genera ( Gyraulus deflectus , G. parvus , Helisoma anceps , Physella gyrina , Planorbella trivolvis , Pseudosuccinea columella , and Stagnicola palustris ) plus the South American freshwater pulmonate Biomphalaria glabrata . They did not feed on eggs of Physa sp. (but killed and ate adult Physa sp. ), nor did they attack the operculate freshwater Bithynia tentaculata , but they successfully attacked Campeloma decisum , the opercula or shells of which had been broken ( Kaczynski et al. 1969).
