Muddler Minnow

A streamer, tied #4–10, carried year round. It is tied against 3 named insects in this book, and stands in when nothing is hatching — all year. Don Gapen, Nipigon River, 1937.

A deer-hair-headed streamer that reads as a sculpin when sunk and a grasshopper when skated, originated by Don Gapen on the Nipigon River in 1937. It is tied on a 3X long streamer hook in sizes 4–10 with brown 6/0 thread: a mottled turkey quill slip for the tail, flat gold tinsel for the body, grey squirrel tail under mottled turkey quill for the wing, and a spun deer hair head clipped to a bullet with the collar left long. It is tied here against the grasshopper, Acrididae, July through September in 60 to 80 degree water, and the sculpin, Cottus spp., available all year from 33 to 72 degrees. It also goes on when no hatch matches the water at all. Fished dead-drift, swung, or skated on the surface, it is one of the few flies that is honestly all three. Carried all season, for trout and smallmouth bass.

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.

A sculpin, and the clipped deer-hair head is what makes it one — broad, blunt and pushing water. Dead-drifted it is a big nymph; stripped it is a baitfish; skated it is a hopper. Drawn at #8 — 23.3 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; Don Gapen, Nipigon River, 1937. — and materials substitute freely: the proportions and the silhouette are the pattern, not the brand of dubbing.

When to fish it

A sculpin, a grasshopper, or a minnow. Fished dead-drift, swung, or skated on the surface — one of the few flies that is honestly all three.

Carried all year. The insects it matches are active all year, in water from 33°F to 80°F.

Target species
