<P> These frogs are found in the central and southeastern United States, with a geographic range from the Eastern Shore of Virginia to southeast Florida, with populations as far west as central Texas, and as far north as Maryland and Delaware . The frogs are considered monotypic, but clinal variation has been observed from Florida north along the Atlantic coastal plain . This possibly may be attributed "to the result of strong selection and / or drift ." </P> <P> Green tree frogs "prefer habitats with plentiful floating vegetation, grasses, and cattails" and are often found in "small ponds, large lakes, marshes, and streams also can be found at night in a backyard swimming pool . </P> <P> Because these frogs are small and easily frightened, they often do not do well with frequent handling . Some specimens do seem to tolerate occasional handling, however, so handling frequency should be determined on an individual basis . The little frogs tend to be nocturnal, and in captivity they will be the most active once the lights are off . Males frequently call most of the year, especially after being misted in the tank . </P> <P> Most American green tree frog females breed once per year, but some have multiple clutches in a single mating season . In a Florida population, "advertisement calls of males were documented between March and September and pairs in amplexus were observed between April and August ." In the Florida population, the average number of offspring in a single clutch was observed to be about 400 eggs . Eggs take between four and 14 days to hatch, with an average of five days . According to the Animal Diversity Web at the University of Michigan Museum of Zoology, "Female size was positively correlated with clutch size, but after the initial clutch, the number of eggs nearly always decreased ." </P>
