Sparkle Dun · Dry fly
A pale wing riding the afternoon glide
A size 14 Sparkle Dun in yellow and olive with a pearl wing, tied to imitate a mayfly dun for trout on smooth water.
A mayfly dun with an upright pearl wing, a split orange tail and a body that shifts from yellow to olive. The rear half is yellow dubbing, the front half olive, all ribbed with fine white thread.

On the water

Yellow at the back, olive up front, with neat white ribs marking each segment. A fan of pearl wing fibers stands tall over the thorax and catches every bit of light. Thin orange tail strands fan out behind like a pair of feelers.
Fish it on flats and slow glides when duns are drifting and fish are sipping. Cast a few feet above the rise and let it ride dead drift, no drag. The wing sits upright and stays easy to follow on flat water.
Ice Wing Fiber for the wing needs to stand straight and fan in a half circle. Build a small thread dam in front, pull the fibers back, and post them up before you dub the head.

Rigging
- Tippet
- 5Xhook size divided by three
- Leader
- Nine feet, tapered — longer and finer in flat water
- Rig on 5X or 6X tippet with a long, fine leader for flat water.
- Dress the wing and body lightly with floatant so it sits low in the film.
- Cast upstream or down-and-across with a slack line for a drag-free drift.
Where and when
- Hatch
- Yellow and olive mayfly duns, typically late spring through summer afternoons
- Target
- Trout
- Water type
- Smooth runs, flats and slow pools on spring creeks and tailwaters
- Also fishes
- Slow eddies and stillwater margins during a mayfly emergence, and as a visible lead fly ahead of a small emerger.

How to tie it
The steps, from first wrap to whip finish (10)
- Mount the size 14 dry fly hook and start the olive 8/0 thread just behind the eye, then wrap a smooth base to the bend.
- Tie in four strands of orange Krystal Flash at the bend, splitting them into two pairs about one shank length long.
- Tie in the white 6/0 rib thread at the bend so it trails behind the hook.
- Dub a slim, slightly tapered body of yellow Superfine over the rear half of the shank.
- Switch to olive Superfine and dub the front half, leaving the forward third bare for the wing and head.
- Wrap the white rib forward in four or five evenly spaced turns and tie it off.
- Tie in a bunch of Pearl Ice Wing Fiber on top at the front of the body, tips pointing forward.
- Pull the fibers upright and build a thread dam in front so the wing stands straight and fans in a half circle.
- Trim the wing to about one shank length tall and trim the butts tight behind the eye.
- Dub a small olive Superfine head in front of the wing, then whip finish and cut the thread.
Proportions (4)
- Tail: about one shank length, split into two even pairs.
- Body: rear half yellow, front half olive, ending at roughly two thirds of the shank.
- Wing: about one shank length tall, fanned in a half circle over the thorax.
- Head: small and neat, taking only the last few turns behind the eye.
Tips (3)
- Use very little dubbing on the body; a thin rope gives a slimmer, cleaner taper.
- Twist the colour change neatly so the yellow and olive meet in a crisp line.
- Brush the Ice Wing Fiber lightly before trimming so the fan looks full and even.
Common mistakes (3)
- Wing leans back over the body: build a firm thread dam in front and add a few turns behind it.
- Tail strands clump together: separate them with a figure-eight of thread before dubbing.
- Head crowds the eye: leave enough bare shank at the start and keep the dubbing sparse.
