Butterflies of the
Amazon and Andes
Family - HESPERIIDAE
There are at least 1038 known species of Grass Skippers (
Hesperiinae ) found in the neotropical region, many of which are
virtually impossible to identify from photographs. A great many of
them are dark brown in colour, and virtually devoid of recognisable
markings. Often, any markings which are present are obscure, and it
can be guaranteed that there will be several dozen near identical
species which can only be told apart by killing them and
microscopically examining the venation and genitalia.
There are 16 species in
the genus Cobalopsis, variously found
from Mexico to Argentina.
Cobalopsis miaba occurs from Colombia
to Guyana, and south to Peru.
The illustrated specimen was seen in disturbed primary rainforest at
an altitude of about 800m. I do not have any further information
regarding it's elevational range, but it is reasonable to surmise
that is occurs from sea-level to at least 1000m.
