The tadpoles of these species have suckers enabling them to hold on to rocks after they hatch. Ī few species use fast-flowing streams, attaching the eggs firmly to the substrate. Other species lay their eggs on the leaves of vegetation hanging over water, allowing the tadpoles to drop into the pond when they hatch. Many use ponds, or puddles that collect in the holes of their trees, while others use bromeliads or other water-holding plants. Hylids lay their eggs in a range of different locations, depending on species. Species of the genus Cyclorana are burrowing frogs that spend much of their lives underground.

The spring peeper ( Pseudacris crucifer) is also widespread in the eastern United States and is commonly heard on spring and summer evenings. North America has many species of the family Hylidae, including the gray tree frog ( Hyla versicolor) and the American green tree frog ( H. The European tree frog ( Hyla arborea) is common in the middle and south of Europe, and its range extends into Asia and North Africa. In the nonarboreal species, these features may be greatly reduced, or absent.

Most hylids show adaptations suitable for an arboreal lifestyle, including forward-facing eyes providing binocular vision, and adhesive pads on the fingers and toes. The subfamilies Pelodryadinae and Phyllomedusinae are sometimes classified as distinct families of their own due to their deep divergence and unique evolutionary history (with Pelodryadinae being the sister group to Phyllomedusinae and colonizing Australia during the Eocene via Antarctica, which at the time was not yet frozen over), but are presently retained in the Hylidae.

Subfamily Pelodryadinae (Australian tree frogs).

Trachycephalus – casque-headed tree frog.

Phytotriades – Trinidad golden treefrogs.Osteocephalus – slender-legged tree frogs.Corythomantis – casque-headed tree frog.The following genera are recognised in the family Hylidae: However, the name 'treefrog' is not unique to this family, also being used for many species in the family Rhacophoridae. The common name of 'tree frog' is a popular name for several species of the family Hylidae. The earliest known fossils that can be assigned to this family are from the Cretaceous of India and the state of Wyoming in the United States. However, the hylids include a diversity of frog species, many of which do not live in trees, but are terrestrial or semiaquatic. Hylidae is a wide-ranging family of frogs commonly referred to as ' tree frogs and their allies'.
