giant Stonefly

[JSzymczyk 0]

here is a giant stone, I think this is the biggest stonefly I've ever seen. I haven't positively ID'd it yet, but superficially it looks just like the "salmonflies" I've seen out west. It looked very fresh, and either came from the Yellow Breeches or the Susquehanna. Both were above flood stage when I found this guy. This would literally take a #2 or #1/0 stimulator to match...

I have seen the nymph in a few small streams that feed the North Branch Potomac and I got positive id on it. So it is possable.

JSzymczyk-

 

Yes, Pteronarcys. There are (5) species known from PA:

P. biloba (Knobbed Salmonfly)

P. comstocki (Spiny Salmonfly)

P. dorsata (American Salmonfly)

P. pictetii (Midwestern Salmonfly)

P. proteus (Appalachian Salmonfly)

 

Differentiating between them requires microscopic examination of genitalia.

we'll leave it with Pteronarcys sp. then, because I left my microscope in my other jacket that day...

 

Thanks for the quick verification!!

We fish that bad boy here on the Snake and Henry's fork but do it in black, grey and orange.
