This one isn't my letter B, but it is extremely cool. When I photograph one of my own, I"ll add it at the end... My husband acquainted me with this photograph which was on a college biology textbook. It was taken by Kjell B. Sandved, a Norwegian author and photographer. He has an amazing collection of the alphabet on butterfly wings. You can see more (and even buy posters) at his website.
