Pseudasellodes fenestraria Rio Kosnipata, Peru © Adrian Hoskins
Introduction
Worldwide there are over 20,000 species in the family Geometridae, of which 2,800 are placed in the subfamily Sterrhinae.

The genus Pseudasellodes is comprised of 9 species. One species - nigrofasciaria, is found on Cuba, while the remainder are distributed variously from Guanacaste to Bolivia and northern Argentina.

All Pseudasellodes species have a similar wing shape although the angularity is more exaggerated in fenestraria. The hyaline windows vary in shape and extent from one species to another - in lacunata they are greatly enlarged and merge inot a single large irregular blotch that covers almost the entire surface of both wings.

Pseudasellodes fenestraria is distributed from Costa Rica to Peru, Bolivia and south-east Brazil.

Habitats
This species inhabits cloudforest at elevations between about 800-1800m.
Lifecycle
To be completed.
Adult behaviour

The hyaline windows in the wings perfectly simulate the nibblings of insect larvae from leaves, and it is likely that the adults rest during daytime among dead leaves on the forest floor.
