The Common Crow (Euploea core) is quite difficult to identify since it is a quite variable species.
The double row of white spots on the back of the forewing are not always present.
However, it has almost always the double row of white spots on the edge of the back of the hindwing whereby the inner spots are more oval than the spots on the outer row (clearly visible on the photos).
