Adults reach 1 to 1.5 inches in length, and females are usually larger than males; newly metamorphosed juveniles are less than 1 inch long.
Brown, olive, tan, or green (sometimes bicolored) with a prominent black stripe on each side from the nostril through the eye and down the sides to the groin; three dark stripes down the back, often incomplete or broken into blotches.
Common, but seldom seen due to its small size and secretive habits.
Lives in moist meadows and forests near wetlands.
Lays eggs in loose, irregular clusters attached to submerged vegetation in quiet water.
Breeds in shallow temporary pools or ponds during the late spring.
Calls are very conspicuous, resembling the sound of a thumb running along the teeth of a comb.
Males call and respond, producing a loud and continuous chorus at good breeding sites, from April to early July, depending on elevation and weather.
