J:son Scud 2 Olive Brown #12

Few aquatic insects are as important to a fish's diet as scuds. These small crustaceans make up a huge portion of the biomass in still waters and slow-moving parts of rivers and streams all over the world, providing a constant, high-calorie meal for fish throughout the year. When fish seem to ignore all other flies, chances are they are keyed in on scuds.

To get the most out of your scud imitation, it is vital to mimic its unique, jerky swimming motion. A real scud propels itself forward by bending its body—almost into a circle—and then quickly straightening out. This creates a "jumping" movement through the water that is irresistible to trout and grayling.

How to fish the J:son Scud:

1. Cast your fly and let it sink to the desired depth.

2. Make a short, quick pull on the line to imitate the scud’s forward jump.

3. Let the fly fall slowly and naturally through the water column.

4. Repeat with brief pauses between each pull.

By imitating this specific behavior, you offer the fish a familiar and easy meal that often triggers a take when nothing else works.

The Stealthy Subsurface Staple – The J:son Scud 2 in Olive Brown is a highly realistic imitation of a medium-sized freshwater shrimp, measuring approximately 14 mm in length. Tied on a size #12 hook, this pattern is designed to match the darker, more camouflaged scuds found in rivers and lakes with organic bottoms, gravel, or submerged roots. The olive-brown tone provides a natural, low-flash profile that is perfect for fooling wary fish in clear water conditions.

This fly features J:son’s signature anatomical precision, with a segmented back and a semi-translucent body that mimics the organic texture of a real crustacean. To make your time on the water more efficient, we have ensured the hook eye is easy to thread, even when using standard leaders. Whether you are nymphing a slow glide or fishing a stillwater bank, the 10 mm Olive Brown Scud is an essential "match-the-hatch" pattern that delivers consistent results by offering fish a high-calorie, realistic target.
