Marbled White and Moon

I captured this image on the Marlborough Downs as a single exposure in camera using a 300mm lens and macro twin flash to light the butterfly. It was tricky to get the camera in exactly the right position for the butterfly, which was waving around in a slight breeze, to be against the disk of the Moon and to keep autofocus locked on the butterfly when it kept trying to wander 400,000 kilometres beyond it. I took 290 images with a success rate of less than 1%.
