The Black Caddis Dry Fly is a pattern we never leave the house without during late summer brookie outings here in Maine. It is the perfect fly to imitate those darker-colored insects dancing over a boiling bog or cascading creek on a sweltering August afternoon. We’re deviating slightly from the original pattern by using CDC for the underwing, which adds a touch of realism while increasing the pattern’s float ability.
- Hook: TMC 100 size 14
- Thread: GSP Veevus black 50 denier
- Ribbing: Herl Flashabou
- Body: Snowshoe Hare’s dubbing
- Under Wing: Slate Grey CDC
- Wing: Deer Hair
- Head: Cement
Start by running the thread from behind the eye to the bend to establish a thread base.
For the ribbing, tie the Flashabou on the shank’s side nearest you, then cover the material with thread down to the bend.
Reinforce the Flashabou by securing a strand of black thread over the flash. Leave the tag ends uncovered, and we’ll finish them later.
We’re using Snowshoe Hare’s dubbing for the Black Caddis’ body. Form a small dubbing noodle onto the thread, then make overlapping turns from the curve to below the eye.
Take the Flashabou’s tag-end and make evenly spaced, open spiral turns around the dubbed body. Secure the material, then clip the excess below the hook eye.
Wrap the securing thread counter-clockwise to the rib up the shank, then secure near the eye.
We’re using a CDC hackle for the underwing. Strip a few fuzzy fibers from the tip, secure it behind the eye, then clip the front-facing excess.
Prepare the wing by clipping a small hair clump from the hyde, stacking them, then removing the unruly fibers.
Finish the wing by securing the deer hair behind the eye. The fibers should extend until they reach the hook’s bend.
Complete a whip finish, then add a dose of head cement. Now it’s time to give the Black Caddis a little twitch on the local trout stream.
