is 1.6-3.5 cm long and has a blunt, pointed head with an occasional triangular marking. Its back and legs are covered with various dark markings. It has a middorsal bright green or brown stripe and the rear of its thigh has a distinct ragged dark stripe. A white bar extends from its eye to its foreleg. The body is slim-waisted and small while the skin is granular and warty. Hind toes are extensively webbed and toe pads are poorly developed (Stebbins 2003).
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).
