This Week's Featured Trout Food - Mahogany Duns
About the easiest way for me to describe the Mahogany Dun mayfly for anglers that fish
the Great Smoky Mountains National Park is to call it the Blue Quill of Summer and Early
Fall. That's because it is very similar to the Blue Quill and in many areas of the country,
some of the species are called Blue Quills. To keep the know it alls from jumping on me
using common names, let me point out the scientific names. The Mahogany Duns are
species of the
Paraleptohlebia genus.  In the Smokies the mollis species (one of those we
call Mahogany duns) hatch in quantities as large as the spring hatches of the
species that we call the Blue Quills. Also, debilis species hatch during the summer and fall
of the year. I think many Smoky Mountain anglers think they are Blue-winged olives
because they do look a little like some of the BWOs. They are completely overlooked by
most anglers although the hatches can be prolific. They are small, dark colored mayflies
usually a hook size 18 or less. Like the spring hatches of
adopitive, they hatch in calm
areas of shallow water adjacent to the faster water. During the typical low water of this time
of the season (or at least it normally is), trout feeding on these mayflies can be very easy
to spook. Often it is necessary to use long, light leaders and tippets and make very careful
approaches. This is tough fishing but can be extremely productive when late summer and
early fall, low, clear water conditions are considered tough to fish by many anglers.

The Mahogany Dun nymphs are crawlers that stay in the current but on the bottom down
between the rocks, gravel and other bottom structure. They prefer freestone streams with
fast to moderate currents.

Prior to hatch times, concentrate on fishing imitations of the nymph in the calmer areas of
water that are near ripples and runs such as pockets, eddies, and calm areas near the
banks. The nymphs are much more effective just prior to a hatch but they will catch trout

The emergers may make several attempts to emerge normally swimming to the surface
Fish the emerger (version shown is our trailing shuck version) without any added weight.
These mayflies often hatch very near the banks in the calm pockets and behind boulders
were the water is calm.

Often, in the summer and early fall when some of the species hatch, they emerge in very
shallow water that is extremely clear. In those cases you may need to use long, light
leaders and tippets and down and across presentations to prevent spooking the trout
feeding on the emergers.

The Mahogany Dun imitation usually works but isn't so easy to fish. As just mentioned,
these mayflies often hatch near the banks and behind boulders where the water is calm
and sometimes very shallow and clear.

Spinners begin to appear within hours after a hatch. Although these mayflies can hatch in
the mornings, they usually hatch late in the afternoons, just before dark. It depends on the
species of Mahogany Dun and if it is hot or cooler early Fall weather. The spinners fall
over the same water they hatch in which is calmer areas nearby moderate to fast moving
water. In most cases the spent spinners collect at the ends of the long slow runs and riffles
and at the heads of pools. Often the spinners fall near dark and seeing the fly is almost
impossible. It is possible to fish another more visible fly a foot or two ahead of the
Mahogany Dun Spinner but we prefer to watch for the small rises and slight leader and
line movement to detect takes.
