When trout are sipping gently in flat water, standard patterns often get refused. You need a Mayfly fly that looks alive. Our Realistic CDC Extended Body Dun is engineered for those critical moments. By combining a lightweight extended abdomen with premium CDC wings, we created a Mayfly fly pattern that doesn’t just float—it lands softly and rides high, exactly like a natural insect.
The “Extended Body” Advantage
Most Mayfly fly patterns end at the hook bend. Real insects don’t.
This pattern features a woven, extended abdomen that projects beyond the hook.
- Realistic Silhouette: Looking up from below, the fish sees the correct length and taper of a real body.
- Better Hookups: By extending the body away from the metal, the hook gap remains clear for better penetration.
CDC: The Magic Material
We use high-grade CDC (Cul de Canard) for the upright wings. Unlike stiff synthetic wings, CDC offers two engineering benefits:
- Natural Buoyancy: The natural oils in the feathers repel water, keeping this Mayfly fly floating longer.
- Micro-Movement: Even in still water, the soft fibers tremble with the slightest breeze, simulating life.
Match The Hatch
This is a versatile imitator. It effectively mimics a wide range of species found across the US:
Green Drakes (Size 10-12): Perfect for those famous western hatches.
March Browns & Cahills (Size 12-14): The go-to choice for spring and early summer evenings.
Presentation Tip: Fish this on a long, fine leader (5X or 6X). Target slow seams where big trout inspect every Mayfly fly before eating.
Common Questions (FAQ)
Do I need floatant?
Yes, but use a powder desiccant (like Shimazaki) specifically for CDC feathers. Avoid thick gels.
Why the extended body?
It provides a larger profile without adding the weight of a larger hook, allowing for a delicate presentation.

1 review for Realistic Mayfly Fly (CDC Extended Body)
First cast with one of these on the Henry’s Fork. Fish came up and took it without hesitation on water where I’d been getting refused all morning. The extended body sits in the film exactly right — it’s not sitting ON the water, it’s IN it, like a real mayfly dun. That detail is everything.
