Asthenia buckleyi, Satipo, Peru  Adrian Hoskins
The genus Asthenia is synonymous with Therinia. There are 12 species, all of which are neotropical in distribution. All the species have a similar wing shape with falcate forewings and a short stubby tail on the hindwings. They vary in ground colour according to species, some being pure white, and others pale yellow or slightly brownish. All have narrow suffused dark bands across the wings. In most species e.g. transversaria, amphira, lactucina and terminalis the bands run diagonally across the wings, but in buckleyi they run parallel to the outer margin.
Asthenia buckleyi occurs in Colombia, Ecuador, Peru and Brazil.
This species is found in rainforest and cloudforest at elevations between about 200-1800m.
The cryptically patterned larva is green with suffused brown blotches and has a curved caudal horn similar to that found on Sphingidae larvae. It rests in a characteristic J-shaped posture on the upper surface of a leaf. If molested it straightens its body and puffs out the thoracic segments revealing a pair of bright blue ocelli.
Adult behaviour

The adults are nocturnal and rest during the daytime under leaves, with their wings fully outspread.
