The Complete Fly Tying Recipe Library

The Zug Bug is a classic attractor nymph created by Pennsylvania fly tyer J. Cliff Zug during the 1930s. Although originally intended to imitate a cased caddis or caddis larva, its general profile can also suggest mayfly nymphs and other aquatic insects. The pattern is commonly dead-drifted through riffles, runs, and pocket water, either alone or as part of a multi-fly nymph rig. It can also be swung at the end of the drift to imitate an emerging insect. Zug Bugs are generally tied in sizes 10 through 16 and are effective for trout throughout the season. When tying the pattern, reinforcing the fragile peacock body and keeping the wing case and tail properly aligned are the main considerations.
