This small sized Grizzled skipper, has quite strongly characteristic red undersides to its hindwing, which is visible in the lower of the two pictures. There is also a line of small white specks in the submarginal area on the upperside of both wings.

This particular specimen was photographed in the Picos de Europa, just north of Potes in August.
