I would say it’s probably a blue quill.

 

[Kyle]

its a may fly. match the color and size. and hold on

 

[Tups]

It is likely a Quill Gordon (Epeorus pleuralis).

What tups said or this. Size had me leaning Hendrickson but I'm no big expert

 

[Boulders]

Yup, Hendrickson or Quill Gordon
Looks like a good day on the stream, have fun!

Too big.

It looks like it has two tails which means not Hendrickson. Good picture but not the best, Would say Quill Gordon.

 

[JeremyW]

yeah, it was a hatch factory, on the east slope of the shenandoah NP... I'm sort of addicted to brookie fishing there.

A couple of good browns will cure you of that 🤣🤣

The spinner pictured lacks the muscular, barred, clinger legs of Epeorus Pleuralis (Quill Gordon). If it was photographed on a high water quality stream it may be Ameletus Ludens.

Here’s an A. Luden dun I photographed recently. Species confirmed by a local aquatic biologist.

BTW, full credit for identifying this mayfly, which I'd photographed on an eastern PA trout stream this year and also on a central PA limestone influenced trout stream in 2022, goes to Don Baylor.
