March Brown Intruder

Articles w/pattern

Another crazy March Brown interpretation... an Intruder. Useful for fishing for salmon and steelhead in fast, clear water.

Originator: 
Martin Joergensen
Pattern type: 
Steelhead fly
Skill level/difficulty: 
A little difficult
Instruction: 
  1. Thread the wire through the hook eye so that the wire sticks out straight.
  2. Mount the shank in a vise so that it's horizontal.
  3. Start the tan thread in the rear of the shank.
  4. Thread the wire through the rear eye on the shank or lay it along the shank if there's no rear eye.
  5. The hook can be tied in point up or down depending on taste and style.
  6. Tie down the wire along the full length of the shank.
  7. Thread through the front eye, bend back and secure the tags.
  8. Wrap the thread to the rear of the fly.
  9. Tie in a yellow GP body feather tip first.
  10. Wrap 2-3 times, tie down and trim stem.
  11. Cut off 10-15 fibers from a GP tail.
  12. Tie in over the hackle in the full circumference of the fly.
  13. Add rubber legs in the same length, also distributed around the shank.
  14. Tie in the yellow tying thread for the rib. Fold it once or twice depending on thickness.
  15. Dub the body all the way to the front of the shank, leaving room for hackles and eyes.
  16. Rib the body in 6-8 open turns.
  17. Tie down rib and trim excess.
  18. Use a partridge tail covert feather for the first front hackle - or a large Brahma hen hackle dyed brown.
  19. Cut off 15-20 fibers from a GP tail.
  20. Tie in over the front hackle in the full circumference of the fly.
  21. Add rubber legs in the same length, also distributed around the shank.
  22. Whip finish the tan thread and cut.
  23. Start the yellow thread.
  24. Tie in the dumbbell eyes under the hook shank.
  25. Secure with plenty criss-cross wraps and form a large head.
  26. Whip finish, cut and varnish.
