Before the days of fancy fly floatants and other products designed to
keep dry flies drier for longer, fly tyers relied heavily on the
physical properties of natural materials to do the trick.
Cul du Canard or "CDC" feather of a common duck is found and harvested
from an area near the animal's preen glands, the center where natural
oils are produced in order to keep the duck warm and dry on the water.
CDC feathers are impregnated with these oils and are extremely water
repellent, an attribute many fly tyers of the past exploited to keep
their flies riding high and dry.
The CDC Rusty Spinner March
Brown is an effective imitation of a March Brown mayfly in the spinner
life stage. This design boasts long and defined split tails and spent
wings of CDC for a smooth and dry flush-with-the-surface drift. This
classic will have trout in a frenzy and it'll perform cast after cast.
- This fly pattern includes naturally water repellent CDC feathers as wings, allowing it to sit flush with the surface through the drift
- The fly sports a thick abdomen, prominent tails, and spent wings of CDC feathers
- March Brown imitation in the spinner life stage
- These bugs are active in the spring from May to June
- Use as a realistic imitation when matching the hatch during a spinner fall
- Fish on a dead drift in medium and slow water; slow-moving eddys can be extremely productive during and after a spinner fall
- Best results early in the morning or later in the evening
- Minimize surface commotion in clear or shallow water by using long leaders and light tippet
- Giving the fly a few twitches during the drift can simulate the struggle of a spent insect and attract opportunistic trout
- When imitating a drowned spinner, it's often useful to use a nymphing strategy with a strike indicator and a short leader
