There are other butterflies very similar to this species, like the P. thersite or P. icarus. Photos alone are often not enough to determine this species.
One indicator that this Male is the P. bellargus are the dark veins continuing out into the white margins of the wing upper- and undersides. On Females this feature is not that prominent.
