Cleopatra or Brimstone?

Cleopatra or Brimstone?

Observation - Cleopatra or Brimstone? - Global. Description: It seems that these species are almost identical but I read that the Cleopatra is more prevalent in the south of France. Beautiful yellowy/orange wings when open. More yellow showing on underwing of female and geography lead me to Cleopatra. Look forward
