Pioneer white butterfly(Belenois aurota) is also a common butterfly of lahore. It is mostly seen in lahore in winter and spring. You can see it often in the Chyrsanthemum flower show flowers.
It is often found on flowers instead of foliage or in open sun. Most of the times it is in gardens but i have seen it on my terrace as well. Like all butterflies it is always found in full sun. All these pictures of pioneer white butterfly are from Lawrence gardens lahore
Because it is a common butterfly in lahore, i guess it is also found in other parts of Pakistan. Probably it migrates from higher mountains to lower plains in winter.
Apart from “Butterflies of lahore”, there will be a post on “Butterflies of Murree hills” soon.
