Spotted Sedge - Additional Information
.............................Fly Fishing Yellowstone National Park
04/23/08

One thing worth mentioning is that anytime you are fishing imitations of the Spotted
Sedge in Yellowstone National Park, there are most likely other species of caddisflies
from other genera of the same family hatching and depositing their eggs at the same
time. There are a lot of different species of them that we will not cover. Species vary
from stream to stream and many are present in most all of the streams in the park but
not in plentiful quantities. Although we don't separately cover them, there are several
species from the
Ceratopsyche genus called Cinnamon Caddis. These caddisflies are
almost identical in behavior and appearance to the
Hydrosyche species. The larvae
and pupae are difficult to tell apart from the
Hydrosyche species and the adults look
very similar except their wings do not have the spots on them.
There is also the Little Sister Caddisflies that hatch during the period of time that the
Hydrosyche species hatch. Then there is the Great Gray Spotted Sedge. We will be
covering both the Little Sister and Great Gray Spotted Sedges.
The bottom line point of this is that any time you are imitating the Spotted Sedge you
are likely to catch trout that are focusing on other species from other genera of net
spinning caddisflies.
Angie and I have been very successful fishing Yellowstone National Park in the late
afternoon and early evenings. During the hot days of July and August it is a cool time of
the day and the
Hydrosyche caddisflies are almost always active irregardless of which
stream you are fishing in the park. As I have previously mentioned, the biggest mistake
you can make is to start fishing fly patterns that imitate the egg layers too early in the
afternoon. Sometimes, it is as late as 9:00 O'clock and even later before the best
activity gets underway.
We have been able to catch several nice trout on many different occasions within just a
short time, less than an hour in many cases, by fishing late in the day.
Do not
underestimate the importance of the caddisfly hatches in Yellowstone and do
not go there unless you are prepared to imitate them
or you will be missing out on
some of the best action it has to offer. Also please be reminded that the different
species of
Hydrosyche caddisflies hatch for a very long time, in fact, they hatch for most
of the fishing season. They also hatch in large quantities on many streams in the park
and can blanket the water at times. They are the most important caddisfly that you can
learn to imitate anywhere in the West.
