Description:  The squirrel treefrog is a small, smooth-skinned frog that can change color rapidly, from green to yellowish brown or brown. It generally has a poorly developed yellowish stripe on each side and sometimes spotting on the back.

Habitats and Habits:  Squirrel treefrogs occur in a wide variety of habitats, ranging from pine savannas to urban backyards. They are found primarily in the Coastal Plain, although they may be introduced into other parts of the state by hitchhiking on garden materials. Squirrel treefrogs are nocturnal and spend the daylight hours hiding under leaves, bark or logs. Eggs are deposited singly at the bottom of shallow, temporary pools, and tadpoles require at least seven weeks to complete metamorphosis.

Call:  Breeding occurs from April to August. Their breeding call is a nasal “waaak, waaak,” repeated about 15 times in 10 seconds. They also have a “rain call,” which is a scolding, squirrel-like rasp usually performed away from water before or during rain storms. Consequently, they are sometimes called “rain frogs.”

Frog Fact:  Squirrel treefrogs and other treefrogs are often seen at night around lighted windows and street lights, where they feed on insects.
