The green treefrog is a small amphibian that can be found in ponds, lakes, marshes and streams.

Appearance:

Green treefrogs reach 1 ¼ to 2 ½ inches long. Females tend to be larger than males. Their color varies from bright green to greenish gray or yellow green on back, with white or cream-colored stomach. Yellow or white stripes may run down the sides of its body, and gold spots may appear on its back. Sticky toe pads on its long toes are used for gripping.

Habitat:

Ponds, lakes, marshes and streams; prefers to live in areas with a lot of floating vegetation and grasses. Most active at night and sleep during the day in moist, shady areas, like the undersides of leaves.

Range:

Found in the central to southeastern United States, from Maryland and Delaware to the southern tip of Florida and as far west as central Texas

Feeding:

These frogs consume small insects and other invertebrates like crickets, moths and flies, and they can often be found clinging to windows or walls, trying to feed on insects that are attracted to light

Predators:

Predators include snakes, lizards, birds and large fish, while the treefrog's coloring serves as effective camouflage.

Voice:

Green treefrogs use a variety of calls to communicate, including mating calls, alarm calls and rain calls. Some have compared the green treefrog’s call to a metallic honk or barking dog. Their call is loudest during damp weather.

Reproduction and Life Cycle:

Green treefrogs breed from March to October in warmer areas and from April to September in milder climates. Hundreds, sometimes thousands of males gather together at a breeding site and call out to attract the attention of females. Females lay approximately 400 eggs, hidden among aquatic vegetation. Males fertilize the eggs once they are laid. About five days after fertilization, eggs hatch. Eight to ten weeks after hatching, tadpoles develop front and rear legs. Once their legs become fully functional, green treefrogs leave the water and venture onto land. Captive green treefrogs can live up to 6 years.

Other Facts:

  • The coloring of the green treefrog may appear brighter yellow when it is calling and a duller green or gray when it is resting.
  • Because they call loudest during damp weather, green treefrogs are believed to be a good indicator of rain.
