Thanks for last night's comments and votes.
This beautifully iridescent female Escher's Blue (Polyommatus escheri) was again taken on the Col des Fillys in the French Alps back in July.
This was the first time that I had come across this species but was not able to identify it till returning home.
Not sure if the background adds or distracts?
