Little Yellow Quills
I'm sure many of you have never head of a Little Yellow Quill mayfly. I fished the streams of the
Smokies for two years before I ever heard of them. I don't mean anything derogatory about this but
quite frankly, it's because the aquatic insects of the Southeastern trout streams have been always
been seriously neglected by anglers. Actually, I didn't ever "hear" of the Little Yellow Quills. I
discovered them in all of the aquatic insect books i had purchased at the time. Later on, I
discovered them in the park and in some areas, in large quantities. In some of the smaller streams,
I found them existing in densities (nymphs per square yard of bottom) as great as the
Quill Gordons,
members of the same family. In many parts of the Eastern U. S., it's a very
common mayfly name, but in many other areas of the east, notably the Southeast, it practically
unheard of.

They begin to emerge about this time of the year and depending on the elevation and the exact
species that uses this common name, continue to hatch for a couple of months.
The Little Yellow
Quill should be very important to fly anglers that fish the park during this time period
because other than the BWOs and Slate Drake, it is the most plentiful mayfly that hatches
in the park during the late Summer and early Fall.
I think many anglers probably call them Light Cahills because I hear that name used during this
same time period and there are certainly not any Light Cahills hatching during this period. About
the only similarity is the bodies of both mayflies are both shades of yellow. The wings are slightly
similar but there's actually quite a bit of difference in them. The Little Yellow Quills are also a little
smaller than the Light or Cream Cahills.

Next, let me make sure no one gets the common name Yellow Quill and Little Yellow Quills
confused. The Yellow Quill is found on most western trout streams. It's a completely different
mayfly sometimes called a Slate Dun. The female Yellow Quill is also called the Pink Lady. It's real
name is the
Epeorus albertae. It's in the same family of mayflies as the Little Yellow Quills.

The Little Yellow Quills are species of the
Leucrocuta genus of the Heptageniidae family of
mayflies. The
aphrodite, hebe, juno and minerva species are the most important ones. When I
discovered the mayfly was found and
documented herein, I was pleased to know I hadn't
completely lost my mind. Notice the
Leucrocuta species shown on this list and also the Heptagenia
species. Species of both these two genera are all called Little Yellow Quills by anglers and so
identified by many fly fishing books as such.
If you click on this page, you will see that species of
the Leucrocuta genus have been found just about everywhere in the park there's water.

We eventually developed our own Perfect Fly patterns of all the stages of life of the Little Yellow
Quills and we have caught many trout fishing imitations of the Little Yellow Quills in the park. It has
always interested me that the know-it-all Smoky Mountain fly anglers that have been fishing "this
hear park" for 50 years, most guides, the self-proclaimed experts in the local mom and pop fly
shops and other bug challenged guys that profess to be experts aren't familiar with this mayfly. If a
yellow mayfly is mentioned during the subject time period, they are always misidentified. The woods
are usually full those that cover up their lack of knowledge about aquatic insects in the park by
declaring such knowledge isn't important to anglers. Have you ever noticed that it's always those
with little knowledge of a subject that are quick to declare something they are not the slightest bit
familiar with as unimportant.

That reminds me. I need to call my neurologist and tell him I don't think
electroencephalography should be of any interest to him.
My scalp is doing fine.
