One of the great things about the classic sowbug is how effective it can be throughout trout rivers in the world. Whether you are on a spring creek or a large tailwater the sowbug can bring trout to the net. Often the best way to fish this pattern is in a nymph rig dragging the sowbug along the bottom of the river. A trout fisherman can never have too many sowbugs. All in all this is one of the universal trout nymphs out there.
