The female lays a single egg on the flower stalk of Cuckoo Flower. The larva hatches and eats only the pods of the plant until it is ready to pupate.
The next 5 images show the larva in sequential stages of development.
The mustard-seed oils in the seedpods make the larvae and adults unpalatable to predators such as birds.
