The photo synthesis blog has the best pictures of whirligig beetles I have ever seen. Maybe the best in existence. I once wrote about whirligig beetles for a natural history column I had in The Bellingham Herald. A very capable photographer, Mame Burns, sprawled on a lake boardwalk for half an hour to get an image of the tiny, frenetically moving insects. She ended up with something in focus, only to have the designer veto it because "It looked like a turd."
