Fly Fishing Yellowstone - Pale Morning Dun - Emergers

The Pale Morning Duns swim to beneath the surface skim to shed their nymphal
shucks. They are suspended in a perfect position for the trout to eat them.
Trout usually do just that, feeding on them with ease. PMDs emerge in the
morning usually from about 9 am to 11am. Like many other mayfly hatches the
activity usually last only a short time, an hour or so, although it may go much
longer on during cloudy, overcast days.

In many cases, the PMD nymphs migrate to calmer, slower moving water that is
very near their normal moderately flowing water habitat just before the hatch.
We suggest you use a long leader and tippet of 6x or even 7x. You will get
better results than you will using something heavier and shorter.

In most all of the situations they hatch, a down and across presentation will work
best. If you can single out an individual trout and fish to it, you will be better off
than blind casting.  We have two types of "Perfect Fly" Emerger flies. One
imitates the emerger when it is more nymph than dun. The other one is a trailing
shuck version that imitates the newly hatched dun before it has shed its shuck.
Either one usually works well.
