Royal Wulff

A dry fly, tied #10–16, carried year round. It imitates nothing in particular, which is the point: it is what goes on when no hatch matches the water temperature.

A high-floating hair-wing attractor tied on a standard dry-fly hook in sizes 10–16 with black 8/0 thread. The tail is moose or elk hair, the body runs peacock herl, a red floss band, then peacock herl again, the wings are white calf tail set upright and divided, and the coachman brown hackle is wound heavy. It imitates nothing — there is no natural behind it, and it belongs in the box as a searching pattern for water showing no hatch at all. The design is built for rough going: fast pocket water and broken riffles, where the stiff hackle and hair wing keep it riding, and the white calf wings stay legible at thirty feet when a drab fly would vanish in the glare. Carried all season, tied for trout, and reliable in the kind of currents that drown lesser dries.

What it looks like

A drawing, not a photograph, and not traced from one. Its proportions were read off 5 independent reference photographs of the pattern and written down as 5 measured characteristics — wing angle, tail length against the shank, how far a hackle fibre reaches — every one of which had to hold across more than one of them before it could be drawn. What survives across many photographs of a fly is the fly.

Peacock, red floss, peacock, and two white hair wings. It matches nothing and floats through anything, which is why it is still in every box in the Rockies and the Catskills alike. Drawn at #14 — 8.0 mm of shank and 4.0 mm of gape on a Tiemco 100.
#10#12#14#165 mm
The bare hook at every size this pattern is tied in, all to the same scale. There is no industry standard behind a hook number, so these are Tiemco 100 measurements and another maker's 10 will differ a little.

What it imitates

It is also tagged for no hatch at all — a searching pattern.

Tying recipe

In tying order. This dressing is the standard one — these patterns have been in the publicrecord for decades — and materials substitute freely: the proportions and the silhouette are the pattern, not the brand of dubbing.

When to fish it

An attractor, not an imitation. Fast pocket water, rough riffles, and any time you need to see the fly at thirty feet.

Carried all year.

Target species

Rivers it fishes well

Rivers with a page here that sit in the regions where the insects this pattern imitates are recorded — which, for a searching pattern, is all of them. It is a claim about coverage, not a report of a fish caught.
