| The following flies are what we recommend for the various mayflies in the streams of Yellowstone National Park. The nymph is weighted and designed to stay on or near the bottom. The emerging nymphs is often the same fly, with no weight. It imitates those mayflies that hatch in 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. It can also be used to imitate those females that deposit their eggs on the surface. 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 dead or dying mayflies.
