River Mist Green Drake Dun

Green Drake Dun · Dry fly
Big drakes lifting off a misty river
A size 10 upright-winged Green Drake dun in olive and yellow, tied to ride high for trout during the drake hatch.
A Green Drake dun stands on the hook with tall dark wings raised over an olive body. Yellow floss ribs the olive dubbing, a moose hair tail trails long behind, and an olive hackle collar holds it high.

On the water

Two dark dun wings stand tall like sails. Below them, an olive body wears neat yellow bands, and a fan of moose hair stretches out past the bend. The olive hackle sits in a soft, spiky collar right under the wings.
Fish it when the big drakes pop off the riffles and drift into the slower water below. Cast above a rise, mend once, and let it ride the seam without drag. A gentle twitch as it nears the fish can mimic a dun trying to fly.
Hen hackle tips make the wing. Match the pair for size, set them shiny sides out, and split them with figure-eight wraps so they stand straight and balanced on the water.

Rigging
- Tippet
- 3Xhook size divided by three
- Leader
- Nine feet, tapered — longer and finer in flat water
- Pair with 4X tippet; the big wings can twist finer line on the cast.
- Dress the hackle and tail with floatant before the first cast, then false cast to dry it between drifts.
- Aim for a long drag-free drift along seams and foam lines; add one small twitch near the fish.

How to tie it
The steps, from first wrap to whip finish (10)
- Mount the hook and start the olive thread one third back from the eye, laying a base to mid-shank.
- Tie in a matched pair of dark dun hen hackle tips, shiny sides out, about one shank length tall.
- Stand the wings upright with thread wraps in front, then split them with figure-eight wraps.
- Wrap back to the bend and tie in a small bunch of moose body hair for the tail, about one shank length long.
- Tie in the yellow floss at the bend and leave it hanging.
- Dub a slim olive body that tapers up to just behind the wings.
- Wind the yellow floss forward in five even open turns and tie it off behind the wings.
- Tie in the olive rooster hackle behind the wings, fibres about one and a half times the hook gap.
- Wrap three turns of hackle behind the wings and two in front, then tie off.
- Build a small, neat olive thread head, whip finish and add a drop of cement.
Proportions (4)
- Wings: about one shank length tall, standing straight up.
- Tail: roughly one shank length past the bend.
- Hackle fibres: about one and a half times the hook gap.
- Body: slim, filling the rear two thirds of the shank and tapering forward.
Tips (4)
- Pick hen hackle tips from the same feather so the two wings match in width and curve.
- Even the moose hair tips before tying in so the tail splays cleanly.
- Keep the dubbing thin; the yellow rib reads better on a slim body.
- Wet your fingers on the floss to keep it flat as you wind the rib.
Common mistakes (4)
- Wings leaning forward: post them with a few wraps behind as well as in front.
- Crowded eye: leave space for the hackle turns and the head when setting the wings.
- Fat body: add dubbing a little at a time and twist it tight on the thread.
- Uneven rib spacing: mark five turns in your head before you start and keep gaps equal.
