Coordinator notes: This is definitely a male Greenish Blue...there are no additional marks on the underside of the Silvery Blue other than the black spots on the wing discs and the blue is more silvery (of course!) with only a narrow (thin) black line at the edge of the wings at the fringe on the Silvery.
