There were few opportunities to see butterflies as the weather was unusually cold and Common Blue (Polyommatus icarus) and Baton Blue (Pseudophilotes baton) flew together in this field. The upper wing underneath has no orange lunules in the Baton Blue and there are two little black marks on the upper wing but otherwise these two blue butterflies are quite similar.
