Blue-winged Olive Dun:
This is our "Perfect Fly"
Blue-winged Olive Dun.
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.
