Fishing The Short-horned Sedge (Caddisflies)

Larvae:
These are saddle case larvae, so named for their horse saddle looking cases.
The larvae get under the saddles however, not on top of them. These are small
domed cases with openings at each end. When they are not bothered, they tend
to stick their heads and legs out of the case. These little cases stick to the rocks
very well and I wonder if the trout ever attempt to eat them when they are in the
cases. They can and do move around on the rocks to feed even though they
are difficult to remove from them.

Although I have read in every fly fishing book that mentions caddisflies that the
larvae of these caddisflies are important in the behavioral drift, I cannot verify
that. I know they come out of their cases and build larger ones and are probably
caught in the currents when they do that. Even though we have taken stream
samples of the drift many times, I have not found any of the little cream looking
worms or larvae of the Little Black Short-horned Sedges in the samples. For that
reason and the fact that I don't know whether or not the trout eat them in their
cases from the rocks, I cannot personally suggest that you fish imitations of the
larvae
