Gray Fox

Gray Fox

The Gray Fox is a classic American dry fly tied to imitate the Stenonema fuscum mayfly — one of the most important and prolific hatches on eastern trout streams, emerging through late spring and early summer and capable of bringing large, selective fish to the surface. With its distinctive mottled wing profile, ginger hackle, and cream-to-tan body, the Gray Fox sits naturally in the surface film and presents a convincing silhouette that matches the natural closely enough to fool even the most cautious rising trout. First popularized by Preston Jennings and later refined by Art Flick, it remains one of the essential Catskill-style patterns for hatch-matching anglers on classic eastern waters — and fishes equally well as an attractor on western freestone streams when pale evening duns or similar species are active.

Pattern Details

• Style: Catskill-style dry fly / Stenonema fuscum and pale evening dun imitation
• Wing: Mallard flank — mottled, upright profile that closely matches the natural wing silhouette of the Stenonema fuscum
• Hackle: Ginger — stiff, high-quality fibres that support the fly on the surface and create a realistic leg impression
• Body: Cream or tan dubbing — slim, tapered abdomen that imitates the pale body of the natural dun
• Tail: Ginger hackle fibres — balanced tail for a level, natural float on the surface
• Profile: Upright-winged Catskill style — sits high and proud on the surface, ideal for moderate to slow currents
• Best water: Eastern freestone rivers and tailwaters during Stenonema fuscum hatches; effective on western streams during pale evening dun activity
• Target species: Trout
• Techniques: Dead-drifted through rising fish during the hatch; effective as a searching pattern between hatches on classic eastern streams; pairs well in a two-dry rig with a smaller trailing emerger
• Sizes available: See variant options

A Catskill classic with a proven hatch-matching pedigree — the Gray Fox delivers the accurate silhouette and natural float that selective eastern trout demand during Stenonema fuscum hatches, making it an essential pattern for any serious dry fly angler.
