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,
lactucina and terminalis the
bands run diagonally across the wings, but in
buckleyi they run parallel to the outer margin.
Colombia, Ecuador, Peru and Brazil.
This species is found in rainforest and cloudforest at elevations
between about 200-1800m.
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.
The adults are nocturnal and rest during
the daytime under leaves, with their wings fully outspread.
