The Perfect Fly Blue Wing Olive Emerger with trailing shuck is an excellent imitation of the actual emerger as it sheds its skin near the surface of the water as it changes into a dun. Blue-winged olive emerge in the afternoons. It looks more like the dun than the nymph. The fly should be fished just under the surface or in the surface skim.
