Introduction
The Pyrginae, popularly known as Flats or Spreadwings, are a cosmopolitan subfamily distributed across temperate and tropical habitats throughout the world. In the Americas there are 990 species.
The genus Potamanaxas comprises of 15 known species, distributed variously from Nicaragua to Bolivia. All species are earthy brown in colour, with white or yellowish bands, which in andraemon and some other species are broken up to form a marbled pattern. Some of these species including andraemon can only be reliably identified by dissecting the genitalia, hence the determination of the illustrated insect as andraemon must be regarded as tentative.
Potamanaxas andraemon is endemic to Colombia.
Habitats
This species inhabits cloudforest at elevations between about 800-1800m.
Lifecycle
Potamanaxas larvae are green with brown heads. They live solitarily within a shelter constructed by silking together leaves of the foodplants, which are Sphyrospermun and other Ericaceae.
