Here again, with a beautiful butterfly, Sahyadri Yeoman.
That is its name, scientifically known as Cirrochroa thais. They are plenty during the flowering seasons and mainly feed on nectar of Compositae flowers. They fly closer to the ground level and sit on the flower long enough to click a picture or two.
Larvae are spiny. Here you can see one hanging in air on a thread-like structure, almost like the silken thread of a cobweb. It was coming down from the overhanging branches of a tree.
The pupa also is spiny and gets attached to nooks and crevices.
