In the neotropical region there are 2365
described species of Hesperiidae. The family is divided into 5
subfamilies, Pyrrhopyginae, Heteropterinae, Megathyminae, Pyrginae
There are over 1040 known species of Hesperiinae in the neotropics.
There are 10 species in
the genus Vacerra, distributed
variously from Mexico to Paraguay. They can be recognised as a genus
by the distinctive pattern of hyaline spots on the forewings. Most
species also have one or more small hyaline spots on the hindwing,
and a blue-green sheen on the thorax.
In some species the
underside hindwings are marbled in shades of brown. In
and molla they are a unicolorous earthy
brown, except for a prominent white or cream stripe. In
molla this stripe is centrally
positioned, while in caniola it is
further out, and in hermesia it is very
close to the edge of the wings.
