Eastern Gray Treefrog Hyla versicolor

St. Louis County
Description: 1 - 2 inches. Although the name may imply that it is always gray, Gray Treefrogs 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.

Similar Species: Cope's Gray Treefrogs are identical in appearance but can be distinguished by their faster, harsher call.

Comments: Absent from southwestern Minnesota.
