Resembling a flying chessboard, marbled whites are amongst my favourite butterflies. I found this one on the Marlborough downs at 7am on a cool, damp July morning. As the butterfly was too cold to move, I set my camera up on a tripod, choosing a position so all of its wings were in focus at f/13 whilst the background was diffuse. Half an hour later the sun broke through, reflecting from beads of overnight dew coating the butterfly. There are even tiny droplets on its eyes.
