The pine woods tree frog (Dryophytes femoralis) is a species of frog in the family Hylidae, endemic to the southeastern United States. Pine woods tree frogs lay eggs in ephemeral water bodies. Eggs generally hatch within 24 hours, and tadpoles metamorphose into baby froglets after 50–75 days at 11–15 mm in length. Tadpoles are remarkably variable; similar to the squirrel tree frog (Dryophytes squirellus), the presence or absence of dragonfly larvae (a predator) induces a dramatic, red-colored tail. Research has shown that chemical cues released by predators and injured tadpoles are enough to trigger these color and body-shape changes, even if there is no direct contact with a predator.
Like many amphibian species' tadpoles, those of the pinewoods tree frog are susceptible to parasitic infection by trematode flatworms. However, tadpoles swim in a manner that does not necessarily reduce the intensity of infection, but reduces the likelihood of these parasites infecting in the head and body region; instead, their swimming behavior shunts parasites to the tail area, where infection by parasites causes fewer harmful effects.

Possible
About 20% of wildlife watchers report a Pine Wood Treefrog sighting in Congaree National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 10th most-seen of the 13 amphibians we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March–April and June–August
In those months about 20% of wildlife watchers report a Pine Wood Treefrog in Congaree National Park on a given day, against under 5% in September to February, the lowest months.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Pine Wood Treefrog sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Congaree National Park, in our data
Congaree National Park is the only park on Wallace's Line with enough records to rate Pine Wood Treefrog sightings: about 20% of wildlife watchers there report one on a given day.
Same genus: Dryophytes
The closest relatives of the Pine Wood Treefrog that you can see in Congaree National Park (genus Dryophytes) are Green Treefrog (about 30%), Cope's Gray Tree Frog (about 30%) and Squirrel Tree Frog (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pine Wood Treefrog is recorded against all the amphibians logged in Congaree National Park (11 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
