Habitat and Ecology
Found on branches and low vegetation in primary and secondary tropical moist forest. Eggs are deposited out of the water on leaves; tadpoles develop in temporary waterbodies. It may occur in lightly disturbed habitat.
It is more common in the central Amazon; it is less common in Colombia and Peru.
No major threats, a widespread species with large areas of suitable habitat remaining. There is some localized habitat loss to general human activities such as agriculture (crops, livestock etc.) and logging (clear-cutting and possibly selective).
In Ecuador, its geographic range overlaps with Reserva Biológica Limoncocha, and Parque Nacional Yasuní. It possibly occurs in Alto Purus in Peru. It was recorded from Parque Nacional Natural Amacayacu in Colombia. In Brazil, it is present in a number of conservation units.
This species was previously within the genus Hyla but has recently been moved to the resurrected genus Dendropsophus (Faivovich, et al., 2005).
