Fly-fishers know the importance of imitating the specific life stage that trout are feeding on, however most current flies only imitate size, shape, and color of the natural insect. Soft-hackled nymphs also imitate movement and behavior. Tying & Fishing Soft-Hackled Nymphs explains how to imitate sub-surface aquatic insects using both traditional and modern soft-hackled nymphs and flymphs along with the most effective presentation techniques. By exploring effective thread and translucent fur body material combinations, as well as game-bird hackle collars, these flies take on life-like properties. These patterns can be fished throughout the water column from the stream bottom--to imitate immature nymphal forms--to the surface mimicking transitional emergers. Drawing on both traditional and evolved patterns and methods, these wingless wet flies will take you beyond for mulaic fishing techniques to unlimited presentation possibilities and will help you catch more trout.
