The wooly worm trout fly is good fished in a variety of ways. Most of us have used them at one time or another. They can be fished dead drifted as a nymph pattern or stripped as a streamer. The wooly worm pattern does not look terribly realistic, but it has stood the test of time for a reason, because on some days it really kicks butt. This is another fly that not only looks like a worm, but in larger sizes easily passes for a baitfish. Used in tandem behind another streamer fly this fly pattern is terribly effective at convincing lock jawed trout to take a bite.
