Description: Carpenter frogs are distinguished by their all brown color with two yellow stripes on each side of the back. Their tail is gray in color and their underside is normally white or yellow. Unlike other frogs the webbing on their toes does not reach the longest toe. Carpenter frogs are recognized by their call which resembles a carpenter hammering, which gives them their name. They have ectothermic, heterothermic and bilateral symmetry. The frog's throat pouch is spherical shaped when inflated. Full grown frogs are medium-sized 1.6 to 2.6 inches.

Habitat: They are usually found in water and rarely on land. The carpenter frog adapted to be able to live in acidic waters. The frog has been observed in cypress ponds, interdunal swales, tupelo swamps, acid swamps, canals, and is associated with sphagnum mats and other vegetation in coffee-colored waters of pine savanna bogs or ponds. They most commonly are found in relatively acidic water abundant Sphagnum or other vegetation leading to being sometimes referred to "sphagnum frogs." They depend on aquatic vegetation in shallow waters for protection and breeding. It is said that carpenter frogs are found in waterways that are tea or coffee colored, where they can easily be camouflaged.

Range: The carpenter frog is found in the Atlantic coastal plains in the United States. From the pine barrens of New Jersey to the bottom of Georgia, the carpenter frog makes its home. The frog is also found, but not common, in Florida.

Found in these States: DE | FL | GA | MD | NC | NJ | SC | VA

Diet: Carpenter frogs eat a majority of aquatic insects and invertebrates such as small crickets, bug larva,and spiders.

Reproduction: Carpenter frogs are prolonged breeders with a breeding season between 2–3 months. The breeding season typically occurs with onset of warm weather in late April and continues until late July or early August. Males maintain territories with a median radius of 3 feet and produce mating calls on most nights of the breeding season. Intensity of the calls varies according to body size, with smaller males having high pitched calls of lower intensity relative to larger males. Calling activity occurs between sunset and sunrise but peaks near midnight. After mating, females lay globular egg masses of 200-600 eggs attached to underwater vegetation up to 8 inches deep. Tadpoles hatch from eggs approximately one week after laying, and remain in this state for approximately 1 year. Between August and September, tadpoles will metamorphose into juvenile frogs.

Status: It is classified as Critically Imperilled in Delaware and Florida. While in Georgia, Maryland, New Jersey, and Virginia it is classified as Vulnerable. And in North Carolina it is classified as Apparently Secure. South Carolina does not have enough data to classify this species.

One of the main reasons that the carpenter frog has become of special concern is due to its susceptibility to habitat loss and degradation. In the 1990s the carpenter frog population in Talbot County was found to be severely decreased as a possible result of habitat degradation. In South Georgia the Carpenter Frog is considered a common species although it has a limited range. Considering that the Carpenter Frog requires wetland areas with large amounts of submerged vegetation for breeding, human disturbances, such as ditching and urbanization, to such environments have and will continue to impact the species.

Because it is known to thrive in acidic waters, throughout time the neutralization of water, specifically in the Delmarva region, has had a great impact on its decline in population because they are unable to adapt. As wetlands become less acidic, it becomes a new habitat for a larger variety of frogs and other species that can thrive in these conditions. It is suggested that predation also plays a role in the decline of their population. These larger frogs include more aggressive species such as northern green frogs which can potentially be a great threat to the carpenter frog. The presence of American Bullfrogs (Lithobates catesbeianus) and Pig Frogs (Lithobates grylio) have also negatively affected the species.

Subspecies: None

Taxonomy: This species was placed in the genus Lithobates by Frost et al. (2006). However, Yuan et al. (2016, Systematic Biology, doi: 10.1093/sysbio/syw055) showed that this action created problems of paraphyly in other genera. Yuan et al. (2016) recognized subgenera within Rana for the major traditional species groups, with Lithobates used as the subgenus for the Rana palmipes group. AmphibiaWeb recommends the optional use of these subgenera to refer to these major species groups, with names written as Rana (Aquarana) catesbeiana, for example.
