BWO Sparkle Dun

Craig Mathews and John Juracek's Sparkle Dun series revolutionized selective-fish fishing. A trailing shuck of Antron mimics the nymphal casing that clings to the adult as it struggles to fully emerge — a critical trigger when fish are keying on cripples. Fish it in the film on slow glides during BWO hatches, which peak in late fall and early spring.

Materials

  • hook: Dry fly hook #18–22
  • thread: Olive 8/0
  • tail: Olive or brown Antron yarn, sparse (trailing shuck)
  • body: Olive-brown dubbing
  • wing: Coastal deer hair, fanned forward (no-hackle style)

Tying steps

  1. Mount hook and tie in a short sparse bunch of brown or amber Antron yarn as a trailing shuck at the bend.
  2. Dub a slim olive-brown body from above the shuck forward to the 2/3 mark.
  3. Cut a small bunch of coastal deer hair; clean underfur and align tips in a stacker.
  4. Measure the deer hair so tips extend to the hook bend; tie in at the 2/3 mark.
  5. Fan the deer hair into a 180-degree semicircle using a post wrap at the base.
  6. Lift the butts upright and wrap tightly at the base to lock the wing in position.
  7. Trim the deer hair butts at a taper and use to form a small smooth head.
  8. Whip finish and apply a drop of UV resin to the wing base to lock it permanently.
