This CDC caddis dry fly in size #16 uses cul-de-canard feathers for a soft, lifelike wing that traps air like the natural insect.
CDC excels on flat, calm water where a delicate presentation matters. Dead-drift it to selective risers.
Present it with a drag-free drift, mending your line as needed to extend the drift through the feeding lane. It also makes a highly visible top fly in a dry-dropper rig, pulling double duty as strike indicator.
