I made this photo on a sunny October day. I was following the butterfly for some time while it was flying from flower to flower, trying to get a decent shot. but the butterfly kept waving with it's wings making it difficult to take a photo with the wings fully open.
But suddenly a cloud came for the sun. Lacking the warmth of the sun the butterfly sat motionless on the flower with it's wings fully open. This allowed me to take this photo with the flash acting as replacement for the sun.
