During studies on different aspects of cricket (Orthoptera: Gryllidae) biology in Hawaii, we observed many toads, Bufo marinus (L.), in areas inhabited by the field crickets Teleogryllus oceanicus (Le Guillou) and Modicogryllus conspersus Walker. The research reported here was intended to determine if B. marinus is a predator of these crickets and, if so, the relative amount of predation on each. We also tested the possibility that B. marinus locates crickets by orienting to cricket acoustical signals.
