KISS A Bug Series - Eastern Pale Evening Duns - Part 2
Nymphs and Emergers

The Eastern Pale Evening Dun nymphs are crawler nymphs that prefer riffles and runs with
moderate currents. This is what separates them from the very similar Sulphurs. You may also
find them in pockets or the heads and edges of pools. They will move to calmer, shallower
water a few days prior to emerging.  

You won't find these mayflies everywhere you fish the trout streams of the Great Smoky
Mountains National Park. The fast water runs and riffles that are typical of the streams are too
swift for the crawler nymphs. Areas of streams with moderate declines rather than steep
declines will have far more Eastern Pale Evening Duns. Moderately flowing water provides a
better habitat for the crawlers.

Crawler nymphs are available for trout to eat from the time they hatch from an egg until they
emerge and hatch into duns. They can hide but they don't get under the rocks like the
clingers. They have less protection from being eaten. Although you can catch trout on an
imitation of the Eastern Pale Evening Dun nymph anytime and anywhere there's a
concentration of the nymphs, the best time to fish an imitation of the nymph is just prior to a
hatch.

You should add some weight on the tippet a few inches above the nymph. You want to add as
little as possible because you want to imitate the nymphs swimming from the bottom to the
surface. The weighted imitation should be presented in a dead drift manner in the riffles, runs
and pockets that are flowing moderately, not fast water. An upstream or up and across
presentation usually works best. You can also use the "high stickin"method of nymphing. You
can also use a strike indicator. These nymphs swim from the bottom to the surface when
hatching and mid depth presentations will work.

The Eastern Pale evening duns usually hatch in the afternoon. The hatch usually occurs
between 1:00 and 4:00 P. M. but usually towards the later part of this time period. When the
nymphs are ready to emerge, they propel themselves to the surface and shed their nymphal
shucks.

The "Perfect Fly" Eastern Pale Evening Dun Emerger, or the Emerger with the trailing shuck,
should be presented in the surface skim of the shallow, slower moving water adjacent to the
moderate flowing ripples and runs where the crawler nymphs are found.

Although we use an up and across presentation, a down and across, on the swing
presentation is often the best way to get the fly to trout feeding on the emerging nymphs in
some smooth water situations. It strictly depends on the water. Smooth flowing water is rare in
the Smokies but you will find plenty of it in most of the tailwaters near the Smokies.

The image below shows the Eastern Pale Evening Dun Emerger with a Trailing Shuck. The plain
emerger usually works best but it is more difficult to fish because it is more difficult to see on the
water. The plain emerger CDC wing should float flush with the surface skim with the body of the fly
hanging down. The trailing shuck version floats higher in the surface skim, level with the surface.
