Mercer's Micro Mayfly
Mike Mercer designed the Micro Mayfly, a slim nymph for imitating tiny mayfly nymphs. It has a gold tungsten bead, a segmented abdomen of stripped peacock quill ribbed with fine wire, and pheasant tail for the tail, wing case and legs over an olive dubbed thorax. It suits clear water and selective trout during mayfly hatches, in both rivers and stillwaters. Tie it in sizes 14 to 18.
