By the flowers of oleina #8 - Blue Leopard

Blue Leopard - a name I give to this butterfly
It is seen only during the season of flowering of the oleina flowers at the park.

Looking like the face of a blue leopard.

Note : I have checked many books about butterflies in this region and I have not seen a picture similar to this one.  There is another variety of this butterfly which has not yet appeared this flowering season.  The other variety has more yellow colours than blue.
