Butterfly ID?

Catonephele numilia (Blue-frosted banner). They’re sexually dimorphic, this is a male. Beautiful species.

Thanks @giant_anteater

I always knew this rarely seen species (I never saw it in my life, alive in butterfly houses nor even pinned in collections) as Grecian Shoemaker more than this new concept of "blue-frosted banner"... but common names are only common names, the important fact is that it's a Catonephele numilia.
