The Red Underwing Skipper is a small, fast-flying butterfly often seen taking salts from damp ground, particularly where puddles are drying out on rutted rough tracks.
This butterfly has a wingspan of 22 to 26mm. The underside of the hindwings are a dark reddish-brown, while the upper side of the wings are dark brown with white spots.
Not recorded in Britain and Ireland, the Red Underwing Skipper is found from North-west Africa to Central Europe including Germany, Poland, the Czech Republic, Austria, Italy, Slovenia and Portugal.
The main larval foodplant of the Red Underwing Skipper is Salad Burnet Sanguisorba minor.
Red Underwing Skippers can be seen on the wing between May and early September. The females usually lay their eggs on Salad Burnet flower buds, and the caterpillars emerge and feed before hibernating; in springtime they emerge and feed again. After pupation, the adults emerge in late spring and summer.
