Marine Blue

Such a tiny, tiny Blue! But, the blue color is only on the upper side of the wings, while the underside is actually brownish (although the girls can also be brownish above). So, to lessen the confusion and in case they're not cooperating by keeping their wings closed when you're taking that shot, it's best to ID these guys by looking at their marks on the underside of the wings.
