Short-tailed Blue

Ok, thanks!

Cupido argiades is the only Lycaenidae with these 2 orange/black spots.

Beautuful colour!!

I think that between Short tailed and Silver studded I would pick the first, for the spots.

Typical lowland migrant Lycaenidae. Sometimes also called Everes argiades. It is the male.

Yes and the identification marks are on the underwings for this group. You too a beautiful photo for all to enjoy. I find white fringe edges on such a small butterfly fascinating.

Thanks! I think you're right, but there are a lot that look very similar to me...

Do not have references for Italy but you can start here:
Order:Lepidoptera(Butterflies)
Family: Lycaenidae (The Gossamer-Winged Butterflies)
and possibly Subfamily: Polyommatinae

lovely !!
