An extremely rare butterfly of the Saint Alias Mountains bordering Yukon and Alaska. 2017. 2,300m asl.
Summer is a short season with long days at this latitude and altitude.
Butterflies eager to mate, collect energy and lay some eggs.
Sometimes they may only have 3 or 4 good days once a year to complete this tricky part of their cycle.
