The following flies are what we recommend to imitate the various mayflies in the streams of the Great Smoky Mountains surface skim or emerging nymphs imitates those mayflies the surface skim just before it hatches. It should be fished near or in the surface skim. The emerging dun with a trailing shuck is part shuck and part dun. It imitates the hatching mayfly and should be fished in the surface skim. The dun is a dry fly that should be fished on the surface imitating the mayfly dun before it departs the water. The emerging adult is a wet fly designed to imitate those mayflies that hatch below the surface from the bottom to near the surface. The spinner is a spent dry fly that imitates the egg layers and dead or dying mayflies.

Note:
Where we note a trickling abundance of a mayfly, we recommend using imitations of them only when you detect a hatch or abundance of nymphs in the water of that particular mayfly. Otherwise, you would be better off using an imitation of a mayfly nymph that is more abundant for the particular area of the stream, or off course, if occurring, a dry fly dun or spinner for the hatch of a more abundant mayfly.

“Perfect Fly” Supper Swimmer Nymph: This is our own pattern for those larger swimming nymphs. By changing the colors of the material used you can match any of  the larger swimming nymphs such as the Slate Drakes found in the Smokies. When it is submerged in the water, its tails, legs and gills move with the currents and imitates the large swimmers well.
