A streamer, tied #2–8, carried year round. It is tied against 1 named insect in this book — all year.
A heavy bottom-hugging streamer on a 4X long hook in sizes 2–8, tied with olive 6/0 thread. Olive and tan rabbit strip forms the tail and body, a sculpin helmet or wool head gives the flat wide profile, mottled hen or Whiting soft hackle stands in for the pectoral fins, and the weight is deliberately heavy — this fly must be on the bottom. It imitates the sculpin, Cottus spp., a baitfish present all year in water from 33 to 72 degrees. The retrieve follows the animal: short strips with pauses, right along the bottom, because a sculpin cannot hover, and a fly that swims steadily mid-column imitates nothing. Any olive-and-tan wide-headed pattern will do the job, dead-drifted or swung, and it fishes best in low light. Carried all season for trout and smallmouth bass.
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.
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.
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.
| Hook | 4X long streamer hook, sizes 2–8 |
|---|---|
| Thread | Olive 6/0 |
| Tail / body | Olive and tan rabbit strip |
| Head | Sculpin helmet or wool head, flat and wide |
| Pectoral fins | Mottled hen or Whiting soft hackle |
| Weight | Heavy — this fly must be on the bottom |
Along the bottom in short strips with pauses. A sculpin cannot hover, so a fly that swims steadily mid-column imitates nothing.
Carried all year. The insects it matches are active all year, in water from 33°F to 72°F.
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.
Same type of fly, or tied for the same insects.
