Thanks to Anup, I stand corrected. This is not a Common Crow, its The Blue Mormon (Papilio polymnestor).

The Common Crow (Euploea core) is a common butterfly found in South Asia. In India it is also sometimes referred to as the Common Indian Crow. It belongs to the Danaid subfamily (Danainae, that is, Crows and Tigers) of the Nymphalidae family, that is, the Brushfooted butterflies.
