Common Dartlet (Oriens goloides) is a butterfly belonging to the skippers super family.

Identification of many genera of the Hesperiidae can prove extremely challenging as there are many lookalike species with obscure markings where positive identification of a species may only be possible with dissection and examination of the genitalia.
