Argyrogrammana comprises of 33 described species, all
restricted to the neotropical region. All are small butterflies
which share a common wing shape, but the colours and patterns vary
considerably from species to species. The wings of
Argyrogrammana stilbe for example are
yellow, covered with dozens of tiny reddish dots; while
trochila has a metallic blue ground
colour and is decorated with a series of fine black stripes.
Argyrogrammana sticheli in common with most species in the
genus is sexually dimorphic. In males the forewing is mostly black,
with patches of metallic blue in the post median and subapical
areas, while in the female the orange is deeper in hue, and on the
forewings is restricted to the basal area.
This species is found in
the Amazonian lowlands, from Guyana and Venezuela, south to Mato
Grosso in Brazil, and probably beyond.
appears to be confined to the Amazonian lowlands, at altitudes
between about 200-600m.
The larvae feed on
sexes tend to be found singly, often sharing their habitats with
Euselasia species. They have an erratic but not particularly
rapid flight, and settle habitually under the leaves of ferns and
other low vegetation.
