Scud
A simple but essential pattern that imitates freshwater scuds (Gammarus), which are a primary food source for trout in tailwaters, spring creeks, and stillwaters. The Scud is a year-round producer that every fly box should contain.

How to Tie the Scud
- 1
Step 1
Mount curved scud hook in vise. Optionally wrap lead wire on the shank for weight. Start thread and secure the wire.
The curved hook mimics the natural curled posture of a scud.

Step 2
Tie in a few short hackle fibers at the bend for the tail. Tie in the copper wire for ribbing at the same point.
Scud tails are very short—just a few fibers.

Step 3
Tie in a strip of Scud Back or clear plastic at the bend on top of the shank.
Cut the shellback material to about 1.5x the hook gap width.

Step 4
Dub a full, cigar-shaped body from the bend to behind the eye using Sow-Scud dubbing. The body should be fattest in the middle.
Keep the dubbing slightly loose—you'll pick it out later.

Step 5
Pull the shellback strip forward over the top of the dubbed body. Tie down securely behind the eye.
Stretch the shellback slightly for a smooth appearance.
- 6
Step 6
Counter-wrap the wire ribbing forward in 5-6 evenly spaced turns over the shellback. Tie off and helicopter-trim the wire.
Ribbing segments the body and secures the shellback.

Step 7
Optionally add short antennae at the head. Whip finish and trim. Pick out the dubbing along the underside with a bodkin for legs.
Picked-out dubbing fibers imitate the scud's many legs.
