Name the pattern

Not sure if this is a stone or a stimulator. Not that it couldn't be either.
Let me know what you think.
Thanks, Byron

Up on the Au Sable River in Michigan that would be called a "Mattress Thrasher"!

Essentially a Improved Sofa Pillow variant...oh yes, I guess some might call it a "Stimulator," but that's a different story...

[kbproctor]

Thrasher? Stimulator? I think that fly is one "Foxy Hooker".

[Allan]

Does anyone know if the name of Randall Kaufmann's dry fly was the 'Stimulator' or 'Simulator'? I've heard both names at various times and I don't have any of the old Streamborn catalogs to check.

"Underwing" Stimulator

Interesting history...

Also like that variation - The Mini Hot - developed by Greg Garcia:

Allan, It's called a Stimulator in Kaufmann's "Tyjng Dry Flies" (1991). That fly looks like the offspring of Brooks Stone meets Stimulator.

[Jayatwork]

Allan, part of the confusion might be because Randall also had a fly called the Simulator, which was a simplified stonefly nymph.

Byron, I wouldn't really call that fly a Stimulator since it lacks the Palmered thorax.

[Byron haugh]

Definitely a Stimulator.

But I have to add that I have never tied nor fished a Stimulator.

And I do fish stonefly dries around 60-70 days a year, April through August.

John.
Ever use a Soffa Pillow or a Marcella's Trout Fly for a Salmonfly?

[NJTroutbum]

That would be half Stimulator and half Sofa Pillow. With a little hint of a Bird's Stone thrown in.

My fly of choice for that application is the Satsop Stone, which was a blend of the Stimulator and Bird's Stone as well.
