Close-up of a butterfly Citrus Swallowtail (papilio demodocus)

The Citrus Swallowtail (papilio demodocus)is one of our more common butterflies. It is large with a wingspan of about 85mm. They lay their eggs on citrus trees. I caught this one in the garden and he was frienly enough to crawl on my hand and let me take the following two photographs.
This is a close-up section of the wing. Sometimes I think I should get a microscope for pictures like these.

These were taken of one I found in the garden. He was on his last legs and sat perfectly still while allowing me to take these pictures.
