It occurs in the intestine of its definitive hosts. Hosts recorded in the wild include the least bittern (Ixobrychus exilis), roseate spoonbill (Platalea ajaja), great blue heron (Ardea herodias), striated heron (Butorides striatus), stripe-backed bittern (Ixobrychus involucris), yellow-crowned night heron (Nyctanassa violacea), black-crowned night heron (Nycticorax nycticorax), osprey (Pandion haliaetus), Neotropic cormorant (Phalacrocorax brasilianus), and marsh rice rat (Oryzomys palustris). In the marsh rice rat, it infected 9% of rats examined in a 1970–1972 study in the salt marsh at Cedar Key
