Had a chance to go to a butterfly exhibit with my camera recently. There were literally thousands of them in this enclosure – it was really amazing. They would land on your shirt or your hat (you had to go through a special screening to check that no butterflies weren’t “hitchhiking” out of the enclosure on you)..
It was good fun trying to capture them up close, and try get them in focus. Here are a few results (click to make the pictures larger):
