In this paper, 62 species of carabid beetles are listed as prey of frogs. Records are from the literature and a stomach contents study.
During the period May to October 1973, I collected and examined the stomach contents of 2 bullfrogs, 45 green frogs, 504 northern leopard frogs and 7 wood frogs from southern Quebec in order to learn whether carabid beetles are major or minor prey of frogs.
