Default Sparkle Dun SBS

[Center]Sparkle Dun SBS
The Sparkle Dun is another in our upcoming series of beginner lessons. This pattern shares construction methods with many other patterns and together with the X Caddis (which imitates caddis and uses the same inexpensive materials) you can match many of your stream's hatches by just varying body color, wing shade and hook size. Coming soon will be additional step by steps for CDC versions of both the Sparkle Dun and X Caddis, which follow the same basic tying steps but are a bit easier to tie in smaller sizes. Both the Sparkle Dun and the X Caddis are very effective flies. They sit in the surface film as opposes to most hackled patterns which sit above it. These are generally used in slow to medium current Click the image to open in full size.
Type of fly Dry Fly, Mayfly Dun (subimago), Mayfly Emerger
Originator of pattern Craig Mathews, Ennis, MT based on previous patterns with similar hair wing construction. These include Bob Nastasi's and Al Caucci's Comparadun (which uses a split fiber tail instead of a shuck) which in turn was based on Fran Better's Haystack, a fast water pattern with a deer hair tail that floats like a cork.
Tied and submitted by peregrines
Level of tying experience needed to tie this pattern Beginner, a fairly simple pattern using basic tying skills. Another excellent dry fly pattern using inexpensive materials.
Techniques covered Selecting a proper amount of dubbing and applying it to directly to a single strand of thread (Direct Dubbing)... Cleaning, stacking and measuring bundles of hollow hair... transferring hands after stacking... proportions and creation of an Arc Wing.... laying a twisted thread foundation... mounting a hollow hair wing using a Soft Loop.
Materials from left: These are the same materials used in the X Caddis. Zelon (in a hank) or Antron (on card) is used to form the shuck material... Short fine deer hair sold as "Comparadun hair" or "Coastal Deer Hair" is used to form the wing. It comes in a variety of natural shades of brownish gray from dark to light to medium. Bleached pieces are also available as are some dyed colors. You will need a Hair Stacker to align the tips of the hair for the wing... Under the hair stacker are two packages of different types of Cul de Canard (CDC) feathers, which make great wings for small hooks instead of deer hair that are much easier to tie We'll also be adding a CDC X Caddis SBS. Dry Fly Dubbing: a fine synthetic dubbing like SuperFine or Fly Rite is a good choice. Dubbing is usually available in dispensers with 12 color assortments or individual packs of colors. Shown here are 12 color assortments Superfine Group 1 (top) and Superfine Group 2, a dubbing cube with small batches of 30 colors also from SuperFine, and an individual pack of dubbing from Fly Rite.

Materials Listed in order of tie in:
Hook Standard Dry Fly size 12-20 Note: a Sparkle Dun tied with a Compardun deer hair wing can be tied from size 12 to 20, but working with hair on smaller hooks can be difficult at first. For now, try using hair on hooks from size 12-16.... Using a CDC wing for smaller hooks is much easier, and X Caddis and Sparkle Duns can be tied from size 16 to a small as you want to go. (Because of the shorter length of CDC tufts, they're not practical above size 16.)
Thread Danville Flymaster 6/0, Uni 8/0 or similar. Your choice of colors to match body (orange used here for visibility), Gray Danville's Flat Waxed Nylon here
Shuck Antron or Zelon The shuck imitates the trailing skincase of the mayfly nymph, the rest of the fly is meant to represent the emerging mayfly dun. These can vary in color, but an amber or light brown is a good place to start
Body Various, but many use a synthetic dry fly dubbing like SuperFine or Fly Rite, your choice of color to match naturals
Wing Short fine deer hair usually sold as "Comparadun" or "Coastal Deer" Hair. Comparadun hair comesin a range of natural grayish brown shades from dark to medium to light, and bleached. An option for sizes 16 and smaller is to use one of more CDC feathers for wing in place of deer hair
Head Thread immediately behind eye of hook around shank and butts of wing trimmed to form a wedge shaped caddis head.
Step by Step
Tie on behind the eye saving 1 eye-width of bare shank for the head.... Twist the thread by spinning the bobbin clockwise (clockwise looking at bobbin from above) to build a firm foundation for the attachment of the wing over the around the 75% point of the shank Click the image to open in full size.
Cut, clean the fuzz from the butts and stack a bundle of hair. As with the wing on the X Caddis, twist the bundle between both hands to compare it's thickness to the hook gap. The twist should be about 1/2 the hook gap or a little less. Too much hair in a thicker bundle will be difficult to attach securely to the shank. Too little and the arc wing will not provide enough flotation Click the image to open in full size.
With the tips aligned from stacking the hair, measure the wing length to be as long as the shank length. In the next step, we will attach the wing using a soft loop and tight wraps as explained in the X Caddis SBS, except that the wing tips will be pointing over the hook eye in the Sparkle Dun, not rearwards as in the X Caddis Click the image to open in full size.
Attach the hair bundle with the tips forward over the eye... Except for the direction of the tips, the procedure is the same using a Soft Loop. While firmly pinching both the hair and the shank, put 2 loose wraps of thread around the hair and shank.... While still pinching tightly with your material hand to hold the bundle in place, lift the bobbin straight up to compress the hair and cinch the the bundle to the hook... Still pinching the bundle take several additional tight turns of thread until the bundle seems firmly attached Click the image to open in full size.
If you remove your material hand it should look something like this. The portion facing over the hook eye will be our wing Click the image to open in full size.
Trim the butts by lifting them up and coming in close with your scissors in an Angle Cut Click the image to open in full size.
Stroke the wings rearward and wind the thread tightly around the shank in front of the wing as close to the wing as you can get. Take several tight wraps of thread to build a dam in front of the wing. This will help to both hold the wing upright, and secure the wing in place to prevent it from rolling around the shank. Click the image to open in full size.
Advance the thread to the rear, covering the butts with thread to the shuck tie in point directly above the barb Click the image to open in full size.
Pinch wrap a length of shuck material. The "butt" end of the shuck material should extend right up to the butts..... The trailing end over the rear of the hook should be about 1/2 hook gap behind the bend of the hook, but we will leave it a bit long for now and trim it on the completed fly.... Bind the "butt" end of the shuck material to the shank up to the rear of the wing butts and return with wraps to the rear till you're above the point... Click the image to open in full size.
Select just a wisp of dubbing as shown in the pic Click the image to open in full size.
Wrap dubbing to with in 1 wrap or so behind wing, leaving a space for an additional wrap of dubbed thread. We're reserving this space for now to be able to dub beneath the wing under the shank without leaving any gaps of dubbing Click the image to open in full size.
With the bobbin hanging on the far side of the shank and the bare spot behind the wing, come under the shank in front of the wing and over the shank in front of the wing on the far side of the shank Click the image to open in full size.
Bring the bobbin under the shank behind the wing on the near side and over the shank behind the wing on the far side-- we've just x wrapped under the wing to fill in dubbing on the bottom of the shank Click the image to open in full size.
Come underneath the shank in front of the wing and wrap over the shank in front of the wing a couple of turns to build a dam of dubbing in front of the wing Click the image to open in full size.
Build a neat head of thread wraps directly behind the eye whip and cut thread.. we're almost done. Click the image to open in full size.
Here an identicial hook is held in hackle pliers to measure shuck length to extend 1 gap width past bend of hook Click the image to open in full size.

Special Tying Notes This dressing tied on a size 12-14 hook with a pale pink body, brown shuck, and a medium dark wing to match an Eastern Mayfly, the emerging female Henderson dun. (Hendricksons are a big deal hatch in early spring in the East and Midwest on many streams.) But hook size, body color and wing shade can be varied to imitate virtually any mayfly hatch. This pattern shares construction techniques with many other patterns including the X Caddis and versions using CDC in place of deer hair for the wing. The CDC wing versions of these patterns with SBS will also be added to the library.

Nice SBS and excellent explanation on how to accomplish the X dubbing and make the wing stand up.
