What do you do when you don’t have the right fly–when you know exactly what the trout are eating but you don’t have the right imitation? An Elk-wing Caddis becomes a moth by flattening the wing. A dun becomes a spinner by trimming hackle and upright wings. An adult becomes an emerger by snipping off the wings and trimming the hackle.
