The natural history of the brown frog Rana longicrus was studied for twelve months in the Aoti area, northern Taiwan. Rana longicrus is a diurnal, terrestrial species that lives mainly in hill areas during the non-breeding season. However, during the breeding season, frogs move to lowland areas, particularly ricefields, to breed. Adult females are larger than males. Reproductive data from males and females suggest that the breeding season is from November to March. Froglets were abundant in March, and they reach adult sizes by September. Desiccation and disturbances from human activities were the leading causes of tadpole mortality. Diets consisted of invertebrates of the classes Gastropoda, Oliqochaeta Arachnida, Crustacea, Insecta, and Chilopoda. Seasonal, sexual, and ontogenetic differences in stomach contents were described.
