Physical Description

Species Hyla cinerea

The Green Treefrog is a slender frog , reaching 2.5 inches in length . The color is generally a bright green as seen here. Occasionally specimens may be lighter or even fade to a yellowish green. There is normally a distinct white or yellowish line running laterally along the side of the frog from the snout to the vent , but this stripe may occasionally be reduced or absent. They also can also have yellow flecks on the back. Green Treefrogs may be heard calling anytime from March to October in the South, and during the spring in the northern part of its range .

Other things to look for: The Green Treefrog has large toe pads .

Color:

Skin usually a bright green, but can vary from yellowish to a dull greenish gray. A prominent white stripe extends from the mouth along the side of the body. The length of the stripe is variable. It usually extends almost to the thigh, but is absent in some populations. There may be small gold spots on the back. The belly color is light cream to green. Green Treefrogs often have a few tiny yellow dots on their backs.

Size/Age/Growth

A moderate - sized, slender treefrog, 3.2 - 5.7 cm (1 1/4 - 2 1/4 in) in length .

Habitat

Prefers swamps and forested wetlands with ample ground cover and aquatic vegetation, where it can be found among floating plants or in the vegetation around the water.

Typically found in a lake at a mean distance from sea level of 42 meters (138 feet).[1]

Ecology: Swamps , marshes, and the edges of ponds , lakes , and streams , particularly where there is abundant floating and emergent vegetation . During daytime, rests among cattail blades or other leaves or shaded branches. Eggs and larvae develop in shallow, still water . Males call while perched on plants next to water (up to 5m above surface) or while sitting on floating plants. Larvae occur mainly in dense floating vegetation.[2].

Biology

Diet

An opportunistic feeder and eats small insects and other invertebrates .

Reproduction

This frog breeds from March through October. Fertilization is external. Females lay up to 400 eggs in shallow water with aquatic vegetation. Hatching occurs within a week and transformation occurs in two months.

From a distance , their call sounds like a cowbell. Calling and egg-laying are particularly frequent after rainstorms.

This species interbreeds with the Barking Treefrog. The resulting hybrid is much stockier than the Green Treefrog, but has the Green Treefrog's coloration .

Behavior

During the day, the Green Treefrog likes to hide under waterside vegetation or in other moist, shady areas. Supposedly, this species prefers to walk rather than jump. Known as the "rain frog" due to the fact that it mostly calls during damp weather. They tend to congregate in extremely large groups.
