Gegenes pumilio/nostrodamus complex

The two species Gegenes nostrodamus and Gegenes pumilio are very similar and are very difficult to distinguish with photographs, unless the presence or absence of a dense or sparce cluster of hairs in basal area of ​​the HW is noted. This feature is evident in young individuals but in old individuals, it is usually not immediately visible. Related Coutsis J. G. & Olivier A .: Confirmation of the presence of both Gegenes pumilio (Hoffmansegg, 1804) and Gegenes nostrodamus (Fabricius, 1793) on the Greek island of Crete (Lepidoptera: Hesperiidae).

Photos are presented where this feature is visible.
