Virginia Wildlife Action Plan Rating Tier II - Very High Conservation Need has a high risk of extinction or extirpation. Populations of these species are at very low levels, facing real threat(s), or occur within a very limited distribution. Immediate management is needed for stabilization and recovery.

PHYSICAL DESCRIPTION: This species has dorsal pattern resembling reversed parentheses which may touch at the middorsum to form a X- or H-shaped pattern. The dorsal background color is gray to olive *11407* *1014*. Ventral surfaces are whitish; males have dark throats *1014*. There is a yellow pigment on concealed and lower surfaces of legs. There is typically a white line on the upper lip and a dark triangle between the eyes *11407*. This species is different from other chorus frogs in that it has a stockier body, wide head, large digital pads, and no middorsal strip or spots *1014*.

REPRODUCTION: This species breeds from February to April in shallow quiet ponds, ditches, and small pools along stream margins typically in or near wooded hills and mountains *1014* *11407* *11284*. The mating call is a harsh, raspy "wreenk" or "reek" and may be heard day or night *1014*. Typically 400 eggs are laid in groups of 10-50. Eggs attain an average size of 1.6 mm *11406*. They are attached to vegetation near or in water. Eggs hatch in 4-5 days. Tadpoles are generally about 30 mm and transform in a mean of 55 days *1014* *11406*. Newly tranformed froglets are approximately 8mm long *1014*.

BEHAVIOR: This species is rarely seen except during breeding season *11284*. It is believed to live in forested areas adjoining breeding habitats. It feeds primarily on small insects and other arthropods.

ORIGIN: Native.

LIMITING FACTORS: This is a woodland species often found a long distance from water *11407*. This species requires forested habitats with damp leaf litter *11284*. Adjacent wet areas (typically ephemeral) are required for successful reproduction.

POPULATION PARAMETERS: Mean survival rate of young adult females is 25% *11406*. AQUATIC/TERRESTRIAL ASSOCIATIONS: This is a woodland species found at elevations up to 3500 ft. (1100 m). It is found on forested slopes and hilltops often a long distance from water *11407*. Breeding occurs in small shallow bodies of water in the woods or at its edge. It uses ditches, pools, or stream margins *1014* *11407*.
