Muschampia cribrellum

Muschampia cribrellum, the spinose skipper, is a butterfly of the family Hesperiidae. A species of arid regions, it is found in northern Hungary, Romania, Serbia, Macedonia and Bulgaria, through the Ukraine, southern Russia, up to the Altai and the Amur region.

The length of the forewings is 13–16 mm. This species resembles Muschampia tessellum but is usually smaller, has larger white markings on the upper side of the wings and a distinctively yellow underside of the hindwing. Adults are on wing from May to June. There is one generation per year.

The larvae probably feed on Potentilla species.
