this really is a mystery butterfly:
-it shows a central blueish tinge, which female BA never has
-the orange spots aren´t orange enough for BA
-the orange fringe isn´t complete enough  for BA
-it has no basal spot in the midcel, which normally excludes CB
-it just isn´t a SsB
So what is it?
The only suggestion I would have is that it is an exceptional CB without
basal spot. I don´t know how rare this is, but I have read somewhere that it
