SCUD

Description

The scud fly is a highly effective subsurface pattern used in fly fishing to imitate freshwater shrimp, also known as scuds or amphipods. These tiny, curved-bodied invertebrates are a crucial food source for trout in nutrient-rich waters like spring creeks, tailwaters, and lakes. The scud fly mimics the natural shape and movement of these crustaceans, making it a reliable choice when targeting fish feeding below the surface.

Typically tied with a curved hook, translucent or olive-colored dubbing, ribbing to suggest segmentation, and often a bit of flash or a shellback for realism, the scud pattern comes alive in the water. Some versions include a weighted body or bead head to help the fly sink quickly to the feeding zone.

Trout often feed heavily on scuds, especially in cold months or in waters with strong aquatic vegetation. Fishing a scud under an indicator or as part of a nymph rig can produce consistent strikes in the right conditions.
