Oeneis glacialis - Alpine Grayling 

Oeneis-glacialis-alpine-grayling | PTKbutterflies

The frosted appearance of this species is a joy to see. After one fleeting glimpse in the Alpine passes of Western Switzerland, the two here were found in the Eastern passes. Very fresh and rather well behaved at times, they are very photogenic when it comes to butterfly photography.
