Stonefly nymphs live in clean moving water, and are an important feeding source for both trout and steelhead. All the attributes of the Beadhead Kaufmann Stone with the addition of rubber legs for action that fish just can't seem to refuse. Often times rubber legs make the difference between strikes and just flogging the water. Juvenile steelhead gorge themselves on stonefly nymphs and are therefore imprinted on the returning adult steelheads. A good indicator of steelhead holding areas will be the density of stonefly nymphs in the area. Therefore this pattern will work for steelhead as well as trout. Stonefly nymphs are very poor swimmers and are often knocked off rocks to float freely at the mercy of feeding fish. Use this pattern in faster moving water, year around, for fast vicious strikes. Stoneflies are only found in rivers.
