Imitates adult caddis. The quill segments make a realistic wing silhouette, and the long hackles provide floatation in rough water.
Different caddis species can be imitated by using hook sizes and body colors that match the natural insect.
How to Fish
Dress the fly with floatant and use standard dry fly presentations. In slower water, you might want to trim the underside of the hackle so the fly will ride lower in the water. The mallard quill wing will start to shred after a few fish have wollopped it. Replace the fly when the wing no longer looks realistic.
