Comparadun - Olive

Comparadun – Olive

The Comparadun is one of the most effective flush-film dry fly designs ever developed — a pattern created by Al Caucci and Bob Nastasi that revolutionized selective trout fishing by presenting the fly in the surface film rather than riding high on stiff hackle. The classic 180-degree deer hair wing creates a precise mayfly dun silhouette that sits flush in the film, imitating the natural posture of an emerging or spent dun with a realism that traditionally hackled flies can’t match. The olive variation is tied to match Blue Wing Olives, Baetis, and a wide range of olive-bodied mayflies that are among the most important hatches on spring creeks and tailwaters throughout the season.

Pattern Details

• Style: Flush-film dry fly / mayfly dun imitation
• Wing: 180-degree deer hair — classic Comparadun design that creates a precise mayfly silhouette and allows the fly to ride flush in the surface film
• Body: Olive dubbing — matches Blue Wing Olives, Baetis, and a wide range of olive-bodied mayfly species
• Best water: Spring creeks, tailwaters, and flat water — wherever selective trout are feeding on olive mayflies in the surface film
• Target species: Trout
• Techniques: Dead-drifted flush in the surface film through feeding lanes during BWO and Baetis hatches; most effective on flat water and spring creeks where fish have time to inspect the fly
• Sizes available: 16, 18

A flush-film classic for the most demanding selective trout situations — the Olive Comparadun’s precise deer hair wing and natural olive body deliver the realistic, low-riding presentation that spring creek and tailwater trout key on during BWO and Baetis hatches.
