Dry FliesWillow Fly
The Willow Fly is a delicate stonefly imitation developed by Barry Ord Clarke for autumn grayling fishing on Norwegian rivers. Also known as a Needle Fly, it mimics small stoneflies from the Leuctridae family using CDC materials and Marc Petitjean's twist-and-wrap technique. The pattern sits low in the surface film, accurately replicating the natural's behavior.

Overview
Barry Ord Clarke designed this pattern specifically for the challenging autumn grayling hatches on Norway's Glomma River. The blue dun wing color was chosen for angler visibility rather than exact imitation of the natural's brown coloring. The pattern employs Marc Petitjean's signature "one twist per wrap" technique to create a realistic segmented body without damaging the delicate CDC hackle stem. Best tied sparse to maintain the slim needle-like profile of the natural.

Fishing Tips
Season
Most effective from June through November, with peak activity during August and September when Leuctridae stoneflies are hatching. An essential pattern for late-season grayling fishing.
Presentation
Cast upstream with a drag-free drift. The pattern's low-riding profile requires careful line management to avoid micro-drag. Focus on smooth glides and slower pool tailouts where grayling congregate in autumn.
When to Use
During needle fly hatches when fish are rising subtly to small stoneflies. Particularly effective on overcast autumn days. Look for delicate dimpling rises rather than splashy takes.
Water Type
Best suited for clear, smooth-flowing rivers and streams. Ideal for grayling water with moderate current and complex surface currents that require precise drag-free presentations.
Rigging Suggestions
Fish on a 10-12 foot leader tapered to 6X-7X tippet. Long, fine leaders are essential for the subtle presentations required. Consider upstream or reach casts to extend drift time.
Visibility & Floatation
Sits low in the surface film like the natural stonefly, rather than riding high like mayfly patterns. The blue dun CDC wing aids visibility for the angler while the dark body blends naturally. CDC provides floatation without added treatment.
