Pats Rubber Legs

Pat Rubber Legs

Materials needed:

  • Nymph hook (sizes 6-12)
  • Black or brown thread (size 6/0)
  • Black or brown chenille
  • Black or brown round rubber legs
  • Lead wire (optional for extra weight)
  • Brown or black hackle feather
  • Pheasant tail fibers (optional)


  1. Start by wrapping the thread onto the hook shank, starting from the eye and leaving some space at the front of the hook.
  2. If desired, wrap a lead wire layer at the hook shank's front half for added weight.
  3. Tie in the black or brown chenille at the front of the hook, leaving some space for the head.
  4. Secure the chenille with tight thread wraps, moving towards the rear of the hook.
  5. Attach the rubber legs to each side of the hook, just behind the chenille tie-in point. The legs should extend beyond the hook bend.
  6. Continue wrapping the thread towards the rear of the hook, binding the rubber legs to the shank as you go.
  7. If desired, tie in a few pheasant tail fibers at the rear to form a tail.
  8. Wrap the chenille forward in even wraps, creating a segmented body. Secure it at the front with thread wraps and cut off any excess.
  9. Palmer the hackle feather forward, pulling back any trapped fibers. Secure the tip of the feather with thread wraps.
  10. Create a neat head by building up thread wraps. Whip finish and cut off the thread.
  11. Trim the rubber legs to your desired length, roughly the length of the body.

And that's how you tie a Pat's Rubber Legs fly for fly fishing! Experiment with different colors and variations to match your local waters' specific insect or baitfish patterns. Happy tying and tight lines!


How to Fish Pats Rubber Legs Fly

To fish the Pat's Rubber Legs fly for fly fishing in Colorado, you can follow the technique called nymphing. This involves casting the fly upstream and allowing it to drift naturally with the current, imitating the movement of underwater insects. The Pat's Rubber Legs fly is known for imitating stonefly nymphs commonly found in Colorado rivers.


Here are some key tips 


  • Rig setup: Use a nymphing setup with a strike indicator, split shot weight for depth control, and a tapered leader with tippet. The weight of the split shot can be adjusted based on the depth and speed of the river.
  • Presentation: Cast the fly upstream and mend the line to achieve a natural drift. Keep the line tight to feel any subtle strikes.
    Depth adjustment: Vary the depth at which you fish the fly by adjusting the amount of split shot weight or using a weighted version of the fly.
  • Stonefly nymphs are typically found near the river bottom, so fishing at the appropriate depth is essential.
  • Retrieve techniques: You can also use short twitches or strips to imitate the movement of a drifting stonefly nymph. Experiment with different retrieval techniques to entice strikes.
