Hi Dave,
Our back garden runs down to a brook where there is plenty of Cuckoo Flower and earlier this year I noticed an Orange Tip egg on one of the plants. As this was right on the edge of an undercut bank and in danger of collapse I transplanted the plant and egg to a flower pot and took it indoors to photograph so no problem with movement in the wind. The attached shows the development of the larva over a couple of weeks to pupation. I had placed a couple of green sticks in the pot to support the plant and of course the larva chose one of these on which to pupate
Hope you managed to find your own pupa.
