Habitat and Ecology
This is a nocturnal tree frog of humid lowland and montane forest characterized by rainfall throughout the year. This species can also be found in modified habitats (with some trees) such as pastureland. Eggs are deposited in pools within streams; the larvae develop in these pools.
This species is abundant in Costa Rica. There is no information available on the abundance of this species in Panama.
There is some general habitat loss through deforestation.
Although there are no specific conservation measures in place, the species has been recorded from a protected area (Parque Internacional La Amistad) in Panama. It does not occur in any protected areas within Costa Rica.
This species was previously within the genus Hyla but has recently been moved to the new genus Isthmohyla (Faivovich, et al., 2005).
