Use our varied and realistic stonefly nymph fly patterns to attract and land big fish. Many anglers claim that nymphing is the way to go, since trout spend 90 percent of their time feeding on nymphs under the water’s surface. And given their large size, even in nymph form, we know that stoneflies have to be among the trout’s favorite food sources. Stonefly nymphs are particularly prolific, crawling on the bottom of clean, cold streams across the country where big trout hang out. Browse our durable stonefly nymph patterns and enjoy success on your next angling excursion.
