A naiad of Anax junius (Drury), in final instar, preyed upon 47 mature snails, Helisoma trivolvis (Say), during a period of 63 clays. The feeding behavior has potential significance: (1) with respect to biological control of trematode vectoring gastropods; (2) as a mechanism for vectoring trematodes between snails and birds; and (3) in interpreting structural adaptations and perception in immature oclonates.
