The Chubby needs no introduction. They have caught fish all over the world and mimic a wide variety of prey. Stoneflies, hoppers, crickets, who knows what the fish think it is, but the one thing that is unquestionable is, fish eat these things.
One of our favorite things about this fly is, it's ability to support heavy nymphs for a dry/dropper rig. In addition to that, it's easily visible with it's large white wing.
