Fly Fishing Yellowstone - Dark Red Quill
The Dark Red Quills are not real common mayflies in Yellowstone National Park
but they exist in some of the small, fast water streams. The Dark Red Quill is the
Cinygmula ramaleyl species. There is another species, the Cinygmula  
reticulata,
sometimes called the Pale Brown Dun, that is also found in some of
the small, fast water streams in the park. Both these species are commonly
called Dark Red Quills. They are clinger mayflies that inhibit the fast water of
some western trout streams.

We have not found this mayfly in any large quantities in the park but we have
found both species called Dark Red Quills hatching when nothing else was
hatching. We are late in the year mentioning this mayfly because they start
hatching in a few streams as early as mid July. Most hatches we have run into
were August hatches. The largest number of the insects we have found was in
the Middle River. We have found them in the upper headwaters of Soda Butte,
Falls River, and in a few places in the Yellowstone River. They are probably in
more streams where we have not encountered them at the right time and place.

They are quite different in appearance from most other mayflies and we do
recommend having a few flies to match them with you in the event you do
encounter them.

Nymph:
The nymph is far more effective just prior to the hatch than it is at any other
time. That is because, like most other clinger nymphs, they stay hidden down
between and under the rocks of fast water streams. If you find a hatch occurring
but it hasn't started, try presenting our "Perfect Fly" Dark Red Quill Nymph in the
current seams between the fast water runs and riffles and the slower water. Like
most clinger nymphs, they move to slower water that is close to their normal fast
water habitat when they get ready to hatch.

Presentation:
We recommend an up and across presentation. Several short cast are better
than long ones in the small, pocket water streams these mayflies exist in. You
may also try the "high stickin" method of fishing the nymph. We haven't tried
fishing the nymph in any of the Yellowstone streams because when we have
encountered the hatch, it came as a surprise. We fished the dun and spinner
stages of the hatch. We have never returned to the same stream the following
day, not because of the lack of activity, but simply because we explored other
streams. We have caught trout using the nymph in other streams in the West,
especially in the state of Colorado where this mayfly exist in plentiful quantities
in several streams.
