There are 1100 known species of Satyrinae in the neotropical region.
About 570 of these are placed in the
subtribe Pronophilina - a diverse group of high altitude cloudforest
butterflies, all of which are confined to the neotropical region.
The vast majority are found only in the Andes, but 4 species are
known from the Atlantic cloudforests of Brazil, and there are a
further 6 species that are endemic to Guatemala, Costa Rica or
Mexico. More oddly there is one genus Calisto
that is found exclusively on the Caribbean islands of Cuba and
are a number of
Lymanopoda species characterised by
having a combination of obscurely marked straw-coloured undersides,
and whitish uppersides reminiscent of Pierines. Amongst these are
nevada, lactea and

This is a high altitude cloudforest species, occurring at elevations
between about 2000-3000m.

eggs are round, white or pale greenish white, and laid singly on the
foodplants or on surrounding vegetation. The larvae are typically
pale brown, marked along the back and sides with narrow dark
stripes, and tapering towards each end. The head is large in
proportion to the body and has two short forward-pointing horns. The
tip of the abdomen is equipped with a pair of caudal prongs which
are used to flick the frass away from the feeding area.
The larvae of all known Pronophilina feed on
Chusquea - a genus of bamboo which
grows in thickets, mainly along the courses of streams.

huilana is usually seen as singletons
amidst mixed Pronophiline aggregations "mud-puddling" at damp spots
along roadsides or the edges of streams.
