The green tree frogs love to feed on insects of all kinds. As such their diet comprises of mosquitoes, flies, and smaller insects. It is also very interesting to note that these frogs have a huge preference for the kind of prey that is highly active; the prey size does not come into account. Green Tree Frogs have an average life span of about 2 to 5 years.
Treefrogs prefer to walk or climb using their sticky toe pads and are reluctant to leap. Green Treefrogs can be bioindicators of aquatic contamination, including contamination by many synthetic compounds used in pesticides, herbicides, and medications.
Green treefrogs are sometimes called rain frogs. Some people think that they are good indicators of rainy weather because they call loudest during damp weather. From a long distance, the green treefrog's call sounds like a cowbell. At closer distances its call sounds more like a "quank-quank."
The green tree frog is a summer and wet season breeder and will make use of all types of still water including water tanks, swimming pools, semi-permanent swamps and drainage systems. Before metamorphosing, the tadpoles may grow to about 10cm in total length.
They prefer habitats with plentiful floating vegetation, grasses, and cattails. One study suggested that, in an artificial hardwood forest setting, the abundance of Hyla cinerea is related to the openness of the forest canopy. The study noted that 88% of 331 individuals were found in areas of the forest where the canopy was open. The presence of green treefrogs in the open canopy areas was interpreted as a method for finding prey, which concentrate in sunny areas with dense ground vegetation.
While extreme changes in color, for example turning and staying a very yellow-green or a dark brown, can indicate stress or illness, changing shades of colors is a normal and natural process for these frogs. Part of these variations in color are an indicator of mood changes, and part of them are a means of camoflauge. Green tree frogs will reach an average size of 2 inches with a range of 1&1/4 to 2&1/2 inches in length, snout to vent. Males are usually smaller than females and have yellow to greenish-yellow throats.
They are grass-green colored, usually with a creamy colored line running from the jaw along the flanks. (There are sometimes specimens who don't have this green line, but they are a very small proportion) It looks similar to its European cousin Hyla arboria, except that it is slighlty thinner and longer.
The green tree frog is native to the south-eastern parts of the United States. They are commonly seen in Florida, South Carolina, Arkansas, and southern Georgia in the local shrubbery of the neighborhoods. They can be heard calling at night in the spring and early summer along side lagoons and ponds.
Tree frogs is the popular term for arboreal and semi-arboreal, nocturnal frogs that have toe pads at the ends of their digits. The common name "tree frog" is usually reserved for members of the family Hylidae, but the popular herpetocultural definition also includes the glass frogs (family Centronelidae), reed frogs (family Hyperolidae), and flying frogs (family Rhacophoridae).
Tree frogs are among the most interesting of amphibians, and some of the most popular to keep in captivity. As their names suggests, tree frogs are mainly arboreal, spending most of their time above ground on trees or other plants.
