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 into 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 southeast Brazil.
Habitats
This species inhabits cloud forest 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 the daytime among dead leaves on the forest floor.
