The Alpine grizzled skipper is very rare in Finland. The best place to look for it is the south-western slope of the Saana Fell in Finland’s north-western ”arm”. The upper side of its hind wing usually has only one white speck in the middle of the wing (although it may also be missing). It is this speck (or the lack of it) that differentiates the Alpine grizzled skipper from the northern grizzled skipper, which has many specks and is the second most common skipper in the north.

The Alpine grizzled skipper flies close to the ground, and so quickly that it is difficult to follow. Females lay their eggs individually.
