Here is the fly pattern sheet for Stalcup’s CDC Loop Wing Emerger – March Brown.

Stalcup's CDC Loop Wing Emerger - March Brown |



Daiichi 1160, #12 – 14


8/0 brown




March Brown goose biot


2 brown or tan CDC feathers


Superfine March Brown dubbing



  1. Begin thread on hook and continue part way around bend.
  2. Tie in tail with 3 to 4 thread wraps and trim butts where thorax begins.
  3. Tie in goose biot with notch towards the front and tie in tip first, creating a furled body.
  4. Wrap thread forward over biot tip and partridge butts to create a smooth underbody. Use thread to create a tapered body. Position thread at thorax.
  5. Wrap biot forward. Option: Apply Zap-a-Gap before wrapping biot for extra strength.
  6. Secure biot with thread wraps. Position thread even with hook point.
  7. Select 2 CDC feathers and even tips. Tie in CDC with concave up and feather over end of hook. Take one loose wrap around feather close to the butt. With thread still loose, pull feather backward allowing trapped barbs to be captured. Continue until only tip remains and secure with several thread wraps.
  8. Add dubbing to thread for thorax. Wrap dubbing to create thorax area. Leave one eye length clear to finish fly.
  9. Select a few Partridge fibers and tie on bottom of hook. Length of fibers should touch hook point.
  10. Fold CDC feathers forward over eye and push backwards to create loose wing. Tie off feather.
  11. Whip finish and trim thread.
