Argyronome ruslana (Heliconian sp.)


Argyronome ruslana looks very similar to Argynnis paphia which also occurs in Japan.
Only by looking at the underside of the wings you can tell the difference.
It seems that Argynnis paphia usually flies from June till early September and that Argyronome ruslana flies until October.
