Best seen in photo 1, the spot of colour above the white splash at the lower upper side of the hind wing was yellow. Sorry about the photo quality but, despite that, I’m thinking this butterfly is a Varied Eggfly (Hypolimnas bolina), (and if so, possibly the same Sp as those at Sightings 4667448 &/ 4667452). It would be great if someone can either confirm or deny this identification.
