Basically white with grey marks. Black dots on the edge of the hind wings.
Just outside my house. I thought it was stuck on a bit of cobweb on the grassy weedy vegetation and was dead. As I touched its legs it just grasped my finger and climbed on to it; it wasn't tangled or anything. Maybe just resting. I set it down on the white spider lilies and later, I saw it had found a new resting place on the stem of the plant.
A nice way for Nature to send me a Happy New Year...sharing with my friends on PN and wishing them great spottings the whole year.
