F Fly by Big Y Fly Co.
This pattern was originally developed as a sedge (caddis) emerger in Europe and tied with CDC material.
Designed to mimic small dark caddis or sedge, the F Fly provides a natural appearance and realistic movement in the water.
The CDC material offers excellent natural buoyancy, allowing the fly to float without the need for floatant.

The F Fly looks very realistic and floats perfectly without any floatant. I’ve used it in both morning and afternoon streams and it’s been caught on several occasions. Great for small caddis imitations.

This fly matches the natural emergence of sedge insects well. The CDC material holds its shape and stays on the surface. I’ve fished it in a variety of conditions and it’s proven reliable.

It’s a solid emerger pattern that works well in slow-moving water. A bit more delicate than other flies, but the natural float is impressive and it mimics the real thing well.
