I have never in all my years of turning stones, have I seen a stonefly like this one. Could you please be so kind as to put a name to it. It came from a southern Georgian Bay tributary. Thank You!!!

Hi OldHasBeen-

I believe it to be Pteronarcys dorsata (American Salmonfly).
Best regards,
Roger Rohrbeck
