Dubbing
Also called dub, dubbing material
Dubbing is loose fiber used to build a fly’s body by twisting it onto tying thread or applying it in a loop. It ranges from natural fur to synthetic blends and comes in many textures and colors.

What Dubbing means
In fly tying, dubbing is the fuzzy material that forms bodies, thoraxes, and collars. It is usually applied by twisting a small pinch onto waxed thread, or by trapping fibers in a dubbing loop and spinning it into a rope.
Natural dubbing is often fur or hair, and synthetic dubbing is made from manufactured fibers, sometimes with flash mixed in. Fine dubbing makes slim, smooth bodies for small nymphs and midges. Coarser dubbing builds bulk quickly and can be brushed out for legs and a buggy look.
How it goes on matters as much as what it is. Tight, even dubbing makes a clean taper. Looser dubbing leaves fibers sticking out, which is useful for imitating gills, legs, or a rougher silhouette.
Why it matters on the water
Dubbing is one of the easiest ways to control profile. A tiny change in how much you use, and how tightly you twist it, changes the thickness of a nymph body or the shoulder on a dry fly without changing the pattern.
It also affects how a fly behaves. Some dubbing sheds water and stays slim, and some traps air and looks brighter or floats higher. Knowing that helps when a fly needs to sink faster, ride higher, or simply look less “smooth” in clear water.

- Dry flyA dry fly is a floating fly meant to be fished on the surface, where you can see it and the take.
- MidgeA midge is a small two-winged fly; in fly fishing it often means a chironomid. Most of their larvae and pupae live in water. Midges hatch in every month on many rivers and lakes, and trout eat them year-round.
- NymphA nymph is a subsurface fly meant to imitate an aquatic insect in its immature stage, or a small food item drifting in the current. Nymphs are fished with or without weight, an indicator, or tight-line methods.
- Whip finishA whip finish is the standard knot used to lock fly-tying thread at the end of a fly. It forms a small, neat knot at the head so the wraps do not unravel.
