Stone Creek BH 20 Incher Stonefly Nymph

Stone Creek™ BH 20 Incher Stonefly Nymph

The Stone Creek™ BH 20 Incher Stonefly Nymph is a proven large-profile stonefly pattern designed to imitate the oversized stonefly nymphs that trout actively target throughout the year. Featuring a realistic segmented body, active rubber legs, and a weighted bead head, this fly delivers the lifelike movement and sink rate needed to consistently reach fish holding near the bottom.

Originally popularized during major stonefly and salmonfly hatches, the 20 Incher has become a year-round producer in rivers, freestone streams, and tailwaters where trout key on large aquatic insects. Its buggy profile and substantial silhouette make it an excellent searching pattern, especially in fast currents, deep runs, pocket water, and rocky structure.

The bead head version provides additional weight to quickly reach productive depths while maintaining the natural movement that triggers aggressive strikes.

Fishing Tips:
