Dry FliesCorn Fed Caddis
The Corn Fed Caddis is a chunky, high-floating caddis imitation designed by Lance Egan that has become a go-to pattern for dry fly anglers across the country. The CDC-based wing creates exceptional floatation while maintaining a lifelike, soft profile that lands delicately on the water. A supremely effective pattern that excels in both technical spring creek situations and aggressive freestone fishing.

Overview
This Trident Fly Fishing tutorial showcases Lance Egan's highly productive caddis pattern. The CDC wing provides the fly's signature floatation—CDC traps air bubbles and creates lifelike movement that deer hair simply cannot match. The white poly yarn overwing serves double duty: it adds buoyancy and acts as a sighter for tracking the fly on the water. The trailing Antron shuck imitates the pupal case still attached to an emerging caddis, adding realism to the presentation. Can be tied in olive, amber, and other colors to match local caddis species.

Fishing Tips
Season
Most effective from spring through fall during caddis emergences. Peak productivity occurs April through October when caddisflies are actively hatching and egg-laying.
Presentation
Dead drift with occasional subtle twitches to activate the CDC fibers. The soft landing of the CDC wing makes this fly particularly effective for spooky fish. Also excels as the dry fly in a dry-dropper rig due to its exceptional buoyancy.
When to Use
Best during caddis hatches or whenever adult caddisflies are present on the water. The high-floating profile makes it visible in choppy water while the CDC creates a realistic silhouette from below. Excellent as a searching pattern during summer months.
Water Type
Ideal for tailwaters, spring creeks, and freestone streams where caddis populations thrive. The fly handles technical flat water beautifully while having enough presence for faster riffles and runs.
Rigging Suggestions
Use 9-foot leaders tapered to 4X–5X tippet. Outstanding as a dry-dropper indicator fly—the poly yarn wing provides excellent visibility while the buoyant CDC supports heavy nymph droppers.
Visibility & Floatation
Exceptional floatation from the CDC and poly yarn combination. The white overwing provides outstanding visibility to the angler. Apply CDC-friendly floatant sparingly before fishing; CDC can become waterlogged with repeated dunking.
