The surprise of the trip. Not that we got it, but that it was so rare. We only saw it at this spot. Taking the wide distribution into consideration I had expected it to be more common. Two animals were all we saw. Both days, and probably the same two!

We saw it in the middle of a forest with zero resemblance to any rocky environment, why both the Danish and Swedish names seem to be off from reality.

I'm not sure how to sex the species. Looking at lepiforum.de they seem to be alike...
