CDC Biot Caddis
Pete Steen ties this slim adult caddis for Fly Fish Food, pairing a segmented turkey biot body with a full wing of stacked CDC. The biot gives a ribbed abdomen with very little bulk, while the CDC holds the fly in the surface and forms a tent shape over the body. A ginger collar in front of the wing suggests legs and adds a little more float. Use a light wire dry fly hook so it rides well, and fish it dead drift during a caddis hatch. Tied here on a size 12 hook.

How to Tie the CDC Biot Caddis
- 1
Step 1
Start the thread behind the eye and lay a smooth base back to the start of the bend.
- 2
Step 2
Tie in a turkey biot by its tip at the bend so the rest of it extends past the hook. Bring the thread forward to the front of the body area.
- 3
Step 3
Coat the thread base with a thin film of Z-Ment to help the body hold together.
- 4
Step 4
Clip hackle pliers to the butt of the biot and wrap it forward in close turns, letting the ridge of the biot form the segments.
- 5
Step 5
Tie off the biot at the front of the body and trim the excess.

Step 6
Dub the thread lightly with the cinnamon caddis dubbing and build a small thorax. Leave room behind the eye for the wing and collar.

Step 7
Stack several CDC feathers with their tips even. Tie them in at the front of the thorax with the tips running back past the bend.

Step 8
Trim the CDC butts and cover the cut ends with thread.

Tie in the soft ginger feather directly in front of the wing and trim its tip.
