How variable is P. polytes romulus female?

[Sky Blue]

So far those we found in Singapore are very consistant. By looking at your photos, initially I thought it's the Papilio memnon

[Painted Jezebel]

Yep, I know what you mean, but there is no red at the base of the cell on the forewing. I've seen specimens with extended rose colouration before, but never to this extent.
