Flashback Scud
Materials
- Hook — Wide-gap curved scud/pupa hook, sizes 12-18 (Daiichi 1130 or TMC 2457)
- Thread — 8/0 (70 denier), color to match body: gray, tan, olive, or hot orange
- Weight — .025 lead or lead-free wire, 6-10 wraps along the shank
- Body — Scud/sowbug dubbing, gray or olive; shrimp-pink Ice Dub for the pink/orange dead-scud variant
- Shellback — Clear/pearl scud back, thin skin, or a strip of clear plastic
- Flashback — Pearl Mylar or Krystal Flash strip laid under the shellback
- Rib — Fine copper or gold wire, wrapped over shellback and flash
- Finish — UV clear resin brushed over the shellback for durability and a wet sheen
Tying steps
-
Mount the curved scud hook and wrap 6-10 turns of .025 lead wire over the middle of the shank; leave room at both ends. Cover the wire with thread and build a smooth underbody, ending at the bend.
-
At the rear of the shank tie in the fine wire rib, then a strip of pearl flash (the flashback) and the shellback material, letting all three trail off the back so you can pull them forward later.
-
Dub a tapered, slightly fat body forward to just behind the eye. Keep it buggy; pick out a few fibers on the underside to suggest legs. Gray or olive for a natural, shrimp-pink for the dead-scud version.
-
Pull the pearl flash strip forward over the top of the body and tie it off behind the eye, so the flash shows through as a bright spine.
-
Pull the shellback forward over the flash and secure it at the eye, stretching it so it lies tight and translucent over the back.
-
Spiral the wire rib forward over the shellback and flash in 5-7 evenly spaced turns to segment the body and lock everything down. Helicopter or cut off the excess wire.
-
Build a small thread head, whip finish, and pick out the belly dubbing once more for movement.
-
Brush a thin coat of UV clear resin over the shellback and cure it. This armors the fly against teeth and gives the back the wet shine of a live scud.
Notes
Imitates freshwater amphipods (scuds), the crustaceans that make up a huge share of the trout diet in tailwaters and spring creeks. A plain traditional dressing with no famous originator: dubbed body, wire rib, shellback, updated with a strip of pearl flash under the shellback for the wet, translucent sheen of a live or freshly dead scud tumbling in the current.
