Mahogany Duns - Nymphs
One thing that makes the Mahogany Dun nymphs important to imitate is the fact they are crawler nymphs
that, like the swimming nymphs, cannot hide all that well from the trout. They stay in areas of current but on
the bottom down in between the rocks, gravel and other bottom structure. They prefer freestone streams
with fast to moderate currents and is why they are relatively plentiful in the Smokies. These mayfly nymphs
are very similar to the Blue Quills that hatch early in the year. In fact, they are species of the same genus.

Prior to hatch times, which ranges from now through the next three months depending on the species,
concentrate on fishing the edges of the calmer areas of water that are adjacent to ripples and runs such as
pockets, eddies, and calm areas near the banks. Use an upstream or an up and across presentation, with
or without a strike indicator, depending upon the water conditions and your preference.  You will want to use
added weight to keep the fly down near the bottom. We prefer not to use an indicator.

The nymphs are more effective just prior to a hatch but they will catch trout anytime of the year they have
hatched from eggs. All the streams in the Smokies have a relatively good population of these mayflies.
