Habitat and Ecology
This is a cloud forest species about which very little is known. The larvae presumably develop in water.
Its population status is not known.
It might be threatened by the agricultural activity (such as cultivation of coffee) that is occurring around the type locality.
It might occur in the Zona Reservada Cordillera de Colán, but this requires confirmation.
