Little Yellow Quills - Dun
You want have any trouble finding the Little Yellow Quill duns. They will be flying
around the streams and in the trees and Rhododendron later this month and into
October. You probably want see any drifting on the surface unless it is later on in
the year when the weather has cooled down. As I said yesterday, I think that is
because they hatch during the evenings when the weather is still hot. They are
beautiful yellow mayflies that look somewhat like Light Cahills. That is what most
anglers confuse them with. That is not all bad because both mayflies are clingers
and both of them inhibit the same type of water with one exception that I have yet to
figure out. The Light Cahills will hatch at all elevations in the park and the Little
Yellow Quills seem to hatch at only the mid to high elevations. It probably has
something to do with the different times of the year they hatch but thats only a

We have caught plenty of rainbows and brook trout in the park on our "Perfect Fly"
imitation of the dun but early in the season, I am not sure whether the trout took the
fly for a spinner attempting to deposit her eggs (before they fall spent into the
water) or a dun that just hatched. The spinners fly just over the water and
sometimes lite on the water for a short time when they are depositing their eggs. I
tend to think that is the behavior we were imitating when we have caught fish on a
dun pattern early in the season. When the weather turns cool, near the end of the
hatch period, the hatches will increase in terms of quantities of flies and the duns
can be spotted drifting at the ends of the riffles and runs.

We cast our "Perfect Fly" Little Yellow Quill Dun up and up and across in
the riffles and at the ends of the runs where they empty into the small pools. As I
have said, these mayflies are more common in the small headwater streams in
Great Smoky Mountains National Park. You will find them as low as the mid
elevations but we haven't found any where the streams are of a larger size in the
lower elevations. This means most of the time you will be fishing small streams eight
to fifteen feet wide that have the typical little run, riffle, pool configurations common
to the fast declining elevation of most brook trout streams.
