Hatches Made Easy:

Great Brown Autumn Sedge  (Pycnopsyche species) - Larvae, Pupae
and Adults


These caddisflies build large cases out of sticks. Although I have read that trout
can be taken on imitations of these larvae, I have never tried it. I know they can
crawl around much better than you would think they possibly could. The larvae
themselves are large and would provide a lot of food but so is the wooden cases
they build. I find it difficult to believe that the trout eat a lot of them but it wouldn't
be the first thing I had guessed wrong about.

We have no experience fishing imitations of them.

The pupae crawl out of the water to hatch during the evenings. It is rare to find
one that is in the process of hatching during the daylight hours.

Although we have tried fishing imitations of the pupae several times during the
hatch, we have had little success with it in the Smokies, or anywhere else for that
matter. At locations other than the Smokies, we have fished it up until it was
completely dark and even then, we have had little success. We fish it down and
across and allow it to swing all the way to the banks imitating the pupae crawling
out of the water.   

The adult Great Brown Autumn Sedge is a beautiful caddisfly but most of its size
consist of wings. The abdomen or body of the fly is not that large in comparison
to its overall size.
The females deposit their eggs during the evenings. Every once in a while you
may see one flying during the late afternoon but they are usually in the trees
and bushes throughout the day. When they do deposit their eggs they do so by
crawling down the banks and depositing them in the water.
It is rare that you will see a lot of these caddisflies at any one time and place. It is
usually one or two, here and there. Most likely this is because they deposit their
eggs during the evenings.

Since they are depositing their eggs along the banks it would only make sense
to fish imitations of the female adult along the edges of the banks. We have tried
this late in the afternoons and just before dark several times with little success. I
wish I could report something more appealing for this large caddisfly but I
cannot. If any of you have any thing you can add to fishing this hatch, I would
really appreciate your letting us hear from you.
