Green Drake Dun · Dry fly

A big olive drake lifting off misty water

A Green Drake dun dry fly on a size 10 hook, olive dubbing with a yellow rib, for trout feeding on the drake hatch.

A Green Drake dun sits upright on a size 10 dry fly hook, wings raised high over an olive body. Pheasant tail fibers form the tail, yellow floss ribs the olive dubbing, and an olive hackle collar fans out beneath dun mallard flank wings.

On the water

A dry fly riding the surface of a trout river

Tall dun wings stand over a plump olive body striped with yellow. Long brown tail fibers trail behind, and a loose olive hackle spreads under the thorax like legs on the film. Behind it, the river runs grey and calm under a low fog.

Cast it above a rising fish in a soft run or slow flat, mend once, and let it ride dead drift. In the last light, give it a single small twitch as it nears the feeding lane.

Mallard flank wings need a tidy tie-in. Stand the clump up with a firm dam of thread in front, then split it into two even halves so the fly lands upright and stays there.

Leader
Nine feet, tapered — longer and finer in flat water
  • Rig on 9 ft leader tapered to 4X; the large wings twist finer tippet.
  • Fish it dead drift on the surface; dress the hackle and tail with floatant first.
  • At dusk, swing it lightly at the end of the drift to suggest a dun trying to lift off.

How to tie it

The steps, from first wrap to whip finish (11)
  1. Mount the size 10 dry fly hook in the vise with the shank level.
  2. Start the olive 6/0 thread behind the eye and wrap a thin base back to the bend.
  3. Tie in a slim bunch of pheasant tail fibers at the bend, about one shank length long.
  4. Tie in the yellow floss at the bend on the far side of the hook.
  5. Dub a slightly tapered olive body forward over the rear two thirds of the shank.
  6. Wind the yellow floss forward in four or five open turns and tie it off.
  7. Tie in a clump of dyed dun mallard flank on top, tips forward, about one and a half gap widths tall.
  8. Stand the wing upright with thread wraps in front, then split it into two even halves with figure-eight wraps.
  9. Tie in the olive rooster hackle behind the wing, shiny side forward.
  10. Wrap the hackle three turns behind the wing and two in front, then tie it off.
  11. Build a small, neat olive thread head and whip finish.
Proportions (5)
  • Tail: about one hook shank long, fibers kept in a slim bunch.
  • Body: rear two thirds of the shank, tapering thicker toward the thorax.
  • Wing: height about one and a half times the hook gap.
  • Hackle: fibers about one and a half times the hook gap.
  • Rib: four to five evenly spaced turns over the body.
Tips (4)
  • Keep the dubbing thin on the thread; build bulk with more turns, not fatter noodles.
  • Twist the floss flat before ribbing so each band lies smooth and bright.
  • Leave bare shank in front of the wing so the head stays small and the eye clear.
  • Even out wing tips before tying in so both halves match in height.
Common mistakes (4)
  • Wings leaning back: add a firm thread dam in front of the clump until it stands on its own.
  • Crowded eye: stop the body and hackle a little short and save room for the head.
  • Ribs bunching together: space the floss turns evenly and tie off only after checking the gaps.
  • Overly long tail tipping the fly: measure the fibers against the shank before the first wrap.
