subfamily Pyrrhopyginae comprises 163 species, most of which are
confined to the Neotropics, although a few occur in Mexico, and a
Pyrrhopyginae are characterised by having a massive muscular thorax
and a conical abdomen with compressed segments. The wings of most
species are black, often with a metallic blue sheen, and are swept
back, half covering the hindwings when the butterflies settle.
There are 3 Oxynetra
species - hopfferi which is distributed
from Mexico to Panama; confusa which
occurs in Venezuela, Guyana, Ecuador, Peru and Bolivia; and
semihyalina. All have broad hyaline
bands extending across both wings, and one or more yellow or reddish
bands around the abdomen.
is found on the eastern slopes of the Andes, from Colombia to
This species occurs in the Andean foothills, at altitudes between
about 300-900m. It is invariably found in the vicinity of streams.
I have no
data regarding semihyalina. The larvae
of hopfferi are banded alternately in
black and cream. They live within leaf-shelters, and feed on
Prunus. The pupa is formed within the
final larval leaf shelter. It is waxy-white, with black dots on the
head and abdomen, and has orange markings along the sides.
semihyalina are occasionally seen on the
ground imbibing mineralised moisture from damp sand, usually in full
sunlight. When settled they
usually hold their wings fully outspread.
