Butterflies are notoriously hard to capture photos of if you try to chase them around. We've had this large monarch flitting in and out of the yard this summer, but not stopping much so I was just watching and waiting.
Today he stopped - and what a show he put on. He knew I was there, he spread his wings, turned his body so I could get a shot of the side of the wings, and generally just preened!! When it's right, it's right!
