Where are the black dots located on the male Pieris rapae vs. male Great White upperside?

The male P. rapae upper wing generally shows only one centrally located black dot, while the male Great White's upper wing appears unmarked by dots.

Distinguishing the males requires close attention to upper wing spotting, as differences exist even within the same genus. The male European cabbage butterfly, P. rapae, typically displays only a single centrally located black dot on its upper wing surface. In contrast, the male Great White (P. brassicae) possesses two black dots, but these specific markings are positioned only on the underside of the wing. Consequently, when viewed from above, the upper wing surface of the male Great White appears unmarked by these dots, providing a key distinction from the single spot seen on the male P. rapae.
