Failed attempt at the Ruby

By Troutnut on July 8th, 2019
I tried for a couple hours to fish the Ruby River at a public fishing access site below the reservoir, but nothing was happening. The water was pretty high and off-color, probably thanks to recent thunderstorms. I don't think I even found a strike, but I did collect a couple good bugs.

Male Rhithrogena hageni (Western Black Quill) Mayfly SpinnerMale Rhithrogena hageni (Western Black Quill) Mayfly Spinner View 14 PicturesAlthough I could not find the preserved specimen to examine under my good new microscope, I'm tentatively calling it one Rhithrogena hageni, based on apparent similarity to this specimen, which I was able to positively ID.

The relative angle of the penes (Penes: The paired genital structures of most male insects, which vary widely in form and are one of the main characteristics used for species identification.) is a bit shallower in this specimen, but I photographed another specimen from the same collecting trip (and I think even the same swarm, although I don't recall for sure) as the other one, and it had the shallower angle seen on this specimen. I'm guessing it's just variation within the species.
