Crack-Back Aero PMD
Curtis Fry developed this PMD emerger from his Aero-Baetis style mayfly nymph after watching how the bright yellow body of the natural shows as the wing case starts to split. A touch of fluorescent yellow resin stands in for that crack. In his experience trout often focus on emerging PMDs, which is why he carries emergers and soft hackles for this hatch. Keep the body slim and the taper true to the natural. Tied here on a size 16 hook.
