The gray treefrog is a frog that averages less then two inches in size. A light spot under the eye is characteristic, and the concealed surfaces of the hind legs are washed with orange. The distribution of this species is poorly understood. This treefrog occurs primarily in moist woodlands, thickets and swamps where it breeds from late April to August. Much of its time is spent foraging for insects in small trees or shrubs over the water. It seems to prefer living in hollow, dead trees or under moist, rotten bark and is rarely found on the ground except when migrating to breeding ponds. The call of the gray treefrog is a slow trill, lasting more than a second and resembles the call of the red-bellied woodpecker.
