This species is known from Choco, Antioquia, Valle de Cauca and Risaralda Departments, on the western flank of the western Andes, Colombia. Its altitudinal range is currently recorded as 1,900-1,960m asl but is presumably broader than this.
Habitat and Ecology
It occurs on vegetation next to streams in primary sub-Andean forests. Eggs are laid on the upper surface of leaves and when hatched the larvae fall into the water below where they then develop further.
It is very common.
There are few threats at present to this very common species, because most of its range is in protected areas.
Populations of this species occur in Parque Nacional Natural Farallones de Cali, Parque Nacional Natural Tatamá, and Parque Nacional de Las Orquídeas.
