Short before the butterfly hatches, you can clearly see the wing's pattern through the pupa's skin!

The very big moment: The Swallowtail is hatching!
In the beginning the wings are still tiny. Then it pumps blood into the wing's veins until they reach the final size. Now the wings are drying and the blood is being retacted. Now the butterfly is able to fly.
