Other Common Names: The Rattle-voice Treefrog, Gladiator Frog, Flying Frog, Emerald Eye Treefrog.

Males reach 61 mm, females 73 mm.

A widespread species with a disjunctive distribution. One population ranges from Panama to northern Colombia, Venezuela and into northern Brazil, occurs on both Trinidad and Tobago and throughout the Guianas. The other population is in Brazil's Atlantic Forest.

The Neotropical Treefrog uses a variety of habitats, ranging from humid tropical forests, semi- arid environments, grasslands, pastures and lower montane forests. It is an arboreal and nocturnal using trees, on shrubs and other vegetation near water. The species breeds in temporary pools or along permanent streams early in the rainy season. During the day this frog can be found in bushes, sitting on leaves, it is bright white in color. Some populations lay eggs in rafts that float on the water, other seem to have basins in gravel that forms nests. While this is considered a common widespread frog, in reality it is a complex of cryptic species in need of systematic revision.

Males engage in combat for calling stations and are sometimes referred to as gladiator frogs. Males may call from the edge of the water or while floating on water. They will call after rains, but also call less frequently well into the dry season.
