At Trident Fly Fishing, we believe that having the right emerger patterns in your fly box can make the difference between a good day and a great day on the water. The Sparkle Dun is one of those must-have patterns that every fly angler should know how to tie and fish. This elegant dry fly pattern was designed to imitate the vulnerable stage when mayflies are emerging from their nymphal shuck, making it incredibly effective during active hatches.
What makes the Sparkle Dun so effective is its realistic profile and the subtle flash of the sparkle yarn that mimics the translucent shuck trailing behind an emerging mayfly. The deer hair wing provides excellent floatability while the sparse dubbing body creates a natural silhouette that selective trout find irresistible. Whether you're fishing technical spring creeks or freestone rivers during a prolific mayfly hatch, the Sparkle Dun should be one of your go-to patterns. Best fished in sizes 12-18, this pattern works particularly well during Blue Winged Olive, Pale Morning Dun, and Light Cahill hatches.

Step 1

Start your thread behind the hook eye and wrap a smooth, even thread base extending to the back of the hook shank. Bring your thread forward and stop at the front one-third of the hook shank.
Step 2


Cut a small pinch of Hairline Coastal Deer Body Hair from the base of the skin, keeping the tips aligned. Place the hair on top of the hook shank with the tips facing forward. Using your thumb and index finger, hold the deer hair firmly so it stays completely on top of the shank — do not allow it to roll to the sides. Secure it in place with several tight, firm thread wraps.
Tip: Pinching the hair tightly while wrapping prevents it from spinning around the shank.
Step 3


Trim the butt ends of the deer hair at an angle. Use thread wraps to build an evenly tapered abdomen from the tie-in point back toward the rear of the hook shank.
Step 4


Select a small amount of Hairline Emerger Yarn. Position it so that it extends back to the same length as the deer hair tips. Tie the yarn in on top of the hook shank using firm thread wraps to hold it securely in place.
Step 5

Using tight thread wraps, bind the emerger yarn down along the top of the hook shank all the way to the bend. Trim the excess yarn so it extends approximately one-half inch behind the hook bend to imitate the trailing shuck.
Step 6


Create a small, thin dubbing noodle using Hairline Super Fine Dry Fly Dubbing. Wrap the dubbing noodle forward along the abdomen, making sure to cover the thread completely and building a smooth, tapered body.
Tip: Use a very small amount of dubbing at a time. Too much dubbing adds unnecessary weight and can reduce the flotation of this fly.
Step 7

Create one more small dubbing noodle. Gently pull the deer hair wing and emerger yarn shuck back toward the rear of the fly to expose the hook shank in front of them. Wrap the dubbing noodle in front of the wing and shuck. This creates a small dubbing dam that pushes the wing and shuck upright so they stand straight up off the hook shank.
Step 8

Apply 2–3 whip finishes directly behind the hook eye, making sure the eye is completely clear and free of any materials. Add a small drop of superglue or head cement to the thread wraps for durability.
Step 9

The Sparkle Dun is now ready to fish. This is an excellent mayfly imitation, particularly effective during a hatch when fish are keyed in on emergers struggling out of their shucks. It also imitates a wide variety of other hatching insects. Fish it in the surface film on slow to moderately paced water, and watch for subtle sipping rises.
Good luck and tight lines!

(2)Hi Mark, I’ve had the best success fishing the Sparkle Dun fished in the film. I grease the wing but leave the body and shuck untouched so it will ride lower in the film. Hope this helps, tight lines! -Pat
I tie a lot of emerger patterns that I fish as a wet fly. Is this fished as a dry or as a wet fly or just fished in the film?
