Comparadun - Sulfur

Comparadun – Sulphur

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 Sulphur variation is tied to match the Sulphur mayfly (Ephemerella dorothea), one of the most important and anticipated evening hatches on eastern rivers and spring creeks from late spring through early summer.

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: Sulphur yellow/orange dubbing — matches the warm, pale yellow-orange coloration of the Sulphur dun
• Imitation: Ephemerella dorothea — the Sulphur, one of the most important evening hatches on eastern rivers and spring creeks
• Best water: Eastern rivers, spring creeks, and limestone streams — wherever Sulphurs hatch during late spring and early summer evenings
• Target species: Trout
• Techniques: Dead-drifted flush in the surface film through feeding lanes during Sulphur hatches; most effective during the evening emergence window when fish are rising consistently
• Sizes available: 16, 18

A flush-film classic for one of the most important evening hatches in eastern trout fishing — the Sulphur Comparadun delivers the precise, low-riding presentation and warm yellow-orange profile that selective trout key on during Sulphur emergences.
