I know not butterflies, but these day flying moths are just as pretty, and more butterfly acting than many butterflies!
I saw several this trip. Here's Dysphania militaris.
This one's D. subrepleta. The second photo showing it puddling alongside D. militaris.
The two grey species I saw that were fairly good mimics of Parantica were D. malayanus (above), and D. transducta (below).
