Common Sailor

Hi Rubens, Have looked carefully at your ID, and they really do look alike. But I notice a couple of differences. In Neptis duryodana nesia, the shoulder/neck is red instead of green, the large spots on the forewing seem to have small crescent moon markings underneath them, and Wikipedia says they are found in Malaysia. I saw mine in South India, so i am more likely to go with the other ID, Neptis Hylas, though I will wait for other's confirmation. Thanks a lot for your ID. Every new ID makes me look more closely at the butterfly, and notice things I didn't see before, and hence I learn more. Thank you so much for your interest and input...
