The Hook-Up Series

The 20 Incher is a large, attractor-style stonefly nymph pattern designed to imitate the larger species of stoneflies, which are a significant food source for trout, especially in fast-moving, rocky rivers and streams. The name 20 Incher refers not to the size of the fly itself, but to the size of the trout it is capable of attracting.
