Gray Treefrog Complex (Hyla chrysoscelis/versicolor)
Description: 1 - 2 inches. Although the name may imply that it is always gray, the Gray Treefrog Complex can actually change color from gray to green, tan, or brown. The back may have a random pattern of darker color. The inside of the thigh is yellowish in color, and the toes have large pads on the end that allow them to climb many surfaces.
