Stone Fly

The Stonefly fly pattern encompasses a massive category of both subsurface nymphs and large surface dry flies designed to replicate insects of the order Plecoptera. Stoneflies are a critical protein source for trout, especially in clean, fast-moving, and rocky freestone rivers. Because these insects live as nymphs for one to three years before crawling out of the river to hatch, heavy stonefly nymphs are highly effective year-round staples for fly boxes worldwide.
