CDC Sparkle Dun – Green Drake
Successful anglers from around the world know of the virtues of CDC feathers used in fly patterns to fool the most selective trout.
CDC feather wings used in important mayfly patterns like Baetis, Pale Morning Duns and Green Drakes float like corks, and are the exact coloration and profile to match natural insects’ big trout feed on.
We first used CDC feathers for winging our famous Sparkle Duns several years ago. After many years testing the patterns on Yellowstone Country’s spring creeks and smooth flowing rivers like the Missouri, Bighorn, Firehole, Madison, and Lamar with tremendous success we decided to offer them. They will become a valuable addition to anglers fishing big-finicky surface feeding trout whether in Montana, Yellowstone, Idaho, Patagonia, or other similar environments.

FAQ
What makes the CDC feather wings effective for trout fishing?
CDC feather wings closely mimic the natural coloration and profile of real mayfly insects, allowing the fly to float like a cork and blend with surface insects that trout feed on.
Is this pattern suitable for use in cold or fast-moving rivers?
Yes, the CDC Sparkle Dun has been tested successfully in fast-flowing rivers such as the Missouri, Bighorn, and Firehole, where it performs well on surface-feeding trout.
Can this fly be used in different regions like Patagonia?

Owen Howard –
Fished this pattern on the Madison River and it caught several trout on a light drift. The green drake color matches the natural insects perfectly and floats smoothly on the surface.
Megan Hill –
Great for spring fishing when mayflies are active. The CDC wing stays buoyant and doesn’t sink, which helps it stay visible to trout in clear water.
Jake Newman –
Used it in Yellowstone’s Bighorn River and saw consistent strikes. The fly mimics the real insect well and works especially well in early morning when trout are active.
