Acris crepitans paludicola and Acris crepitans blanchardi are recognized as subspecies. A. c. paludicola has smooth skin with a pinkish patterned coloration. The throat remains pink, even for males during breeding season. A. c. blanchardi by comparison is wartier, bulkier, and heavier with a light brown or gray uniform coloration (Conant and Collins 1991).
Males have more ventral spotting than females (Stebbins 2003).
