RIO's Morrish May DayAfter 40 years of observing mayfly duns on the water and comparing them to the flies we imitate them with, I had a simple but somewhat profound revelation. Duns sit on the water not in the water. Their bodies don't touch the water and their tails are nowhere near the surface. When fish look up at duns, there is nothing more than a light semi round impression of the insect, and that impression is far smaller than the impression of a typical parachute
