ID Request : Osiris Blue ?

[Willem]

Dear,

I currently looking at some older pictures and wondering whether these are Osiris or Minimus ( taken Val D'Herens - Switzerland)

My guess is Osiris .

Thanks in advance.

Hi Willem,

That's a mazarine blue.

EDIT - just saw the second frame - those, I believe, are male little blues, minimus.

EDIT 2

The rear/right butterfly in this picture is osiris from the Val d'Hérens. You can see it has a very much narrower, linear, dark margin than your butterfly and less pronunced dark veins. The one in front is a green-underside blue:
