To a human observer these appear as white spots fringed with blue-violet. They actually consist of a white center overlain by bright ultraviolet iridescence, a colour generated by nanostructures on the wing scale surface. Numerous smaller white spots fringe the fore- and hindwings. The ventral surface lacks any ultraviolet iridescence and consists essentially of banded white markings set against a brownish background. These males exhibit lower body mass per unit wing area, implying lower wing loading, more elongate wings, resulting in a higher aspect ratio, which are also the characteristics used to differ them by their conspecific...
