Polyommatus icarus
Lycaenidae, Polyommatinae, Polyommatus icarus. One of the most common butterflies in Europe and though sometimes tricky to ID. But I am quite confident, that these are Polyommatus icarus.

Beautiful image Ivan, viewed separately would be easy to assume they were separate species.
