Blue Butterfly Beauties

...I can't identify them on the web and I left the Butterfly book at home. I have never seen this blue before. Extra for the under wings if anyone can help me. We are in Rhêmes Notre Dame in Italy, if that helps. Fabulous walk with the rest of the world, but never mind, to the Rifugio Benevolo.

Damon Blues apparently, thanks to intothehills. Many thanks also go to osuzanna our host for Tiny Tuesday.
