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).
