There are two other Butterflies which are almost identical to the C. argiades. The first is the Cupido decoloratus, which doesn't have the orange spots seen clearly on this photo. The other is the Cupido alcetas, which also doesn't have the spots.

The further in the flight-period you come, the more difficult it becomes to determine the C. argiades due to the wear and tear of the wing scales.
