North American population sometime exhibit blue colour inside black spots on hindwings also although they are not so vivd as in Australian V.kershawi.
I wonder if old world V.cardui specimens have blue spots, I only have one specimen from Poland and the spots are all solid black.
Here is another specimen collected in 2017 during invasion. This one has some blue inside black spots.
