A streamer, tied #4–10, carried year round. It is tied against 1 named insect in this book, and stands in when nothing is hatching — all year.

A bucktail attractor in red and yellow with no natural behind it at all, tied on a 4X long streamer hook in sizes 4–10 with black 6/0 thread. The body is flat silver tinsel ribbed with oval silver, and the wing is built in three layers — yellow bucktail, then red bucktail, then yellow bucktail over the top — which gives the fly its banded look and a good deal of movement in current. It imitates nothing in particular; the pattern is tagged for no hatch at all, a searching fly, and there is no pretence of imitation in the colours. Trout, smallmouth bass and steelhead are all targets, and it is carried year-round. The conditions that suit it are stained water and aggressive fish, and it earns its place on dropping water after rain, when visibility is poor and a bright, fast-moving wing gives a fish something to commit to.

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.

Yellow, red, yellow. It imitates nothing and has been catching fish since the 1930s, which is the only defence a bucktail attractor needs. Drawn at #8 — 27.6 mm of shank and 7.0 mm of gape on a Tiemco 100.
#4#6#8#1010 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 4 will differ a little.

What it imitates

Each of these is the same hatch record the app's own panel reads, so a pattern recommended on a river card in the app is recommended for one of the insects below.

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 bucktail with no natural behind it at all. Stained water and aggressive fish.

Carried all year. The insects it matches are active all year, in water from 35°F to 78°F.

Target species

Rivers it fishes well

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