Tree frogs are frogs of the families Hylidae and Rhacophoridae. There is large variation among tree frog species. Many species are not actually arboreal (do not live in trees), but terrestrial or aquatic (live on the ground or in the water). Many tree frogs are green, while terrestrial and aquatic species are duller. They mostly feed on insects and other invertebrates, but some larger species can feed on small vertebrates. The species within the genus Cyclorana are burrowing frogs, sometimes spending many years underground.

The European tree frogs such as Hyla arborea are common in the middle and south of North America, and range into Asia and North Africa. The species become very noisy on the approach of rain and are sometimes kept in confinement as a kind of barometer.
In North America there are many species of tree frog, including Hyla versicolor, a species of grey tree frog, and Hyla cinerea, the American green tree frog. The spring peeper is also widespread in the eastern United States and is commonly heard on summer and spring evenings.
The tree frog is a popular name for several of the Hylidae. Hyla versicolor is the changeable tree toad, Trachycephalus lichenatus is the lichened tree toad, and T. marmoratus the marbled tree toad.
Old World treefrogs are found in India, Sri Lanka, China, SE Asia, Indonesia, Japan and the East Indies, only the genus Chiromantis is found on continental Africa. Most members of this family are arboreal. In many of these the eggs are laid under water and are pushed to the top of the water to get hatched.
The family of the tree frogs is subdivided in 6 subfamilies and 47-49 genera.
