A streamer, tied #2–12, carried year round. It is tied against 5 named insects in this book, and stands in when nothing is hatching — all year.
A black streamer of marabou and chenille that reads as a leech, a sculpin, a big nymph, or none of them at all. It is tied on a 3X long streamer hook in sizes 2 through 12 with black 6/0 thread: a black marabou tail with a few strands of Krystal Flash through it, a black chenille body, black saddle hackle palmered the length of that body, and lead wire or a cone head for weight. The marabou breathes at rest and the palmered hackle pulses on the strip, which is most of why the fly works across so many roles. It is tied here against the giant black stonefly, Pteronarcys dorsata, in May and June from 50 to 62 degrees, and the sculpin, Cottus spp., available all year from 33 to 72, and it also stands in when nothing is hatching. Fished any way at all — stripped, swung, dead-drifted under an indicator — for trout, smallmouth bass and steelhead, in every season.
A drawing, not a photograph, and not traced from one. Its proportions were read off 4 independent reference photographs of the pattern and written down as 6 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.
It is also tagged for no hatch at all — a searching pattern.
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.

Fish it any way at all — stripped, swung, dead-drifted under an indicator. It is a leech, a sculpin, a big nymph, or none of them.
Carried all year. The insects it matches are active all year, in water from 33°F to 78°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.
