Was just trying to distinguish any differences on the underside of the wings between the male and female. The only difference I can see is one has an extra spot on the front of the wing towards it's top. But then that may simply be one wing covering it on the other butterfly.
I believe the butterfly on the left is the male. I can make out "claspers" on the abdomen and, in the family Lycaenidae (Blues), the female is generally larger than the male. This would look fantastic as a print hanging on your wall, Rey.
Best regards as always,
