This photo was clicked at kalu Ganga reservoir construction site at about 6p.m, last June. The temperature was hot and it was a relatively dry season in the vicinity. The size of the butterfly is small and was sitting in a height of about 20 cm above the ground level for a while.
Just looked it up in the butterfly guide and am confused whether it is a Common Silverline or a Plumbeous Silverline. I am positive this is a Plumbeous considering the narrow-ness of the yellow gap between the 3rd and 4th bands from the base. But nwould like to have peer opinion in the case.
