Introduction
There are at least 1038 known species of Grass Skippers ( Hesperiinae ) found in the neotropical region. Among these are several genera in which the butterflies are dark in colour, with the veins on the underside picked out in a contrasting paler shade. These include Apaustus, Callimormus, Lento, Euphyes, Flacilla, Ludens, Molo, Parphorus, Peba, Phlebodes, Radiatus, Venas, Virga and Vehilius. To distinguish between the genera it is necessary to study the venation, and the markings between the veins. In some genera / species the spaces are devoid of markings, while in others there are pale streaks, dashes or spots, in various configurations.
There are 12 known species in the genus Vehilius, of which Vehilius stictomenes is the commonest and most widespread, being found across most of tropical South America.
Habitats
