Malcolm's Scud

Printable Version


The pattern was tied at the Ozark Fly Fishers General Membership meeting on October 22, 2009. The pattern was presented and tied by Malcolm Royse. Scuds are shrimp-like (Not really a shrimp) fresh-water crustaceans. They can occur in huge numbers in lakes and in slack water sections of rivers. When present, they offer trout a delicious morsel that is hard to resist.

  • Tie in the ribbing and back material.
  • Dub body on thread and wrap to eye forming a tapered body on the thick side.
  • Bring back material over the top and secure by counter wrapping the rib, evenly spaced, to eye.

Scuds should be lightly weighted either with lead under the body or with a beadhead. The 2457 hook is curved and represents a resting or drifting scud. The 200R hook is straight and is used for a swimming scud. Match your presentation to the hook style. Color choices: olive-gray, tan, pink, orange

How to Fish

In Streams, tail water and rivers, present the fly with the shallow nymph or wet fly swing presentations; remember, scuds are present in weedy, slow-water stretches. In lakes, use an intermediate line and a slow retrieve.
