Marbled White Butterfly

I was able to shoot these images yesterday day. It is about the right time for this species to emerge so I went to the place I would expect to find them.

I only found three and I believe they had just emerged that morning.

You can observe from the one below the very pale green washed look on the white part of the underwings. This is a sign that the drying process from emerging from the chrysalis had not completed. Although they can fly within about an hour, the wings will take a day to fully harden.
