Like most treefrogs, this species is strictly nocturnal (active at night). It is difficult to observe because of its treetop habitat and its mottled appearance, which blends well with pine tree bark.
The Gray Treefrog occurs statewide, with the exception of apparent absence from the former savannah and prairie habitats of southeastern Wisconsin, where it is replaced by the look-alike species Cope's Gray Treefrog, H. chrysoscelis.

Eastern long-toed salamander larvae in Oregon have been observed feeding on hatchling Pacific treefrog (Hyla regilla) larvae. Cascades frog (Rana cascadae) larvae and fairy shrimp (Anostraca) were other potential prey in the breeding pond [31].
Reproducing tetrataenia require a diet consisting primarily of frogs (juveniles may also feed on salamanders, earthworms and treefrogs). Thus, despite an abundance of mice and fish, where there are no frogs, there are no tetrataenia.
If allowed to overeat and become obese, older Dumpy Treefrogs grow fat layers on the tops of their heads, hence the name "dumpy." White's Tree Frogs have "suction-cups" on their feet and can climb smooth surfaces, such as glass, with ease.
