April Rust Mayfly Wet Fly

Wet fly

Spring light on a cold, clear creek

A sparse mayfly wet fly on a size 14 hook, rust quill body and dun wings, for trout on spring freestone water.

A slim mayfly wet fly with a rust segmented body and long tail fibres that sweep upward. Dun hen hackle tips form the swept wing over a sparse dun collar and a rust thread head.

On the water

A soft-hackle wet fly swinging through mid-water

Rust segments run the length of a thin quill body. Two long tan tail fibres arc up and away behind it. Grey dun wings lie back over the top, and a wisp of soft hackle trails underneath.

Fish it in the runs and riffle tails when the first mayflies come off in spring. Cast across, let it swing on a tight line, and give a small lift as it rises at the end of the drift. A slow dead drift through a seam works too.

Stripped hackle quill makes that crisp segmentation. Soak it for a few minutes before wrapping so it lies flat without splitting, then let each wrap just touch the last.

  • Tie on 5X or 6X tippet; a clinch knot keeps the slim profile intact.
  • Swing it across and down, then lift the rod tip slowly as the line straightens.
  • Add a small split shot a foot above the fly to reach deeper runs.

How to tie it

The steps, from first wrap to whip finish (10)
  1. Mount the hook in the vise and start the rust thread one eye-length behind the eye, wrapping a thin base back to the bend.
  2. Tie in four to six Coq de Leon fibres at the bend, about one and a half hook shanks long, and let them flare slightly upward.
  3. Keep the tail butts trimmed short and bind them down evenly so the rear of the body stays thin.
  4. Tie in a soaked rust stripped hackle quill by its thin tip at the bend.
  5. Wrap the quill forward in touching turns to two-thirds up the shank, building a slight taper, then tie off and trim.
  6. Tie in a dun hen hackle by the tip just ahead of the body.
  7. Make two sparse wraps of hackle, tie off, and stroke the fibres back and down under the hook.
  8. Match two dun hen hackle tips, concave sides together, about one hook shank long.
  9. Tie the wings on top, swept back over the body, and trim the stems.
  10. Build a small, neat rust thread head and whip finish.
Proportions (4)
  • Tail: about one and a half times the hook shank length.
  • Body: covers the rear two-thirds of the shank with a slim taper.
  • Wing: reaches just past the bend of the hook.
  • Hackle: fibres roughly as long as the hook gape, two wraps only.
Tips (4)
  • Soak the stripped quill for a few minutes so it wraps without cracking.
  • Stroke the tail fibres between finger and thumb to encourage the upward curve.
  • Keep the hackle sparse; a few fibres move better in current than a full collar.
  • Leave a clear eye-length behind the eye so the head stays small.
Common mistakes (4)
  • Lumpy tail tie-in fattens the body; trim the butts short and wrap them flat.
  • Overlapping quill wraps hide the segments; let each turn just meet the last.
  • Wings tied too tall look like a dry fly; pinch them low and swept back before tightening.
  • Too many hackle wraps make it bushy; stop at two turns.
