Ken Morrish's May Day

Umpqua's May Day callibaetis fly is the most important Western stillwater mayfly of all. There is no insect more important to the Western stillwater angler than the Callibaetis. None... A slender, realistic mayfly body is clearly visible to the angler because of a large parachute post. This parachute dry fly rides low, yet floats very well--perfect for cloudy days when the trout are sippin'.
