Rana limnocharis from rice fields of Nara, central Japan, fed on a wide variety of prey animals. Arthropods constituted 94.8% in number and 52.9% in volume of total prey items. Among prey taxa, ants (26.9%) comprised the largest proportion in number, and earthworms (36.2%) in volume. One froglet and one tadpole were also recovered from frog stomachs. The generalized food habits of R. limnocharis would ensure the establishment of populations of this species outside its natural range.
