Frog pond September 15, 2018. Carpet pond. It was surrounded by boundless elderberries, and the shade they provided allowed frogs to breed all summer. We had tadpoles up through October! October 1, 2018. American bullfrog, Lithobates catesbeianus. I counted, at any given time, an average of 8 frogs sunning on the stones.
