Mayfly ID

[jeremymcon]

I live fairly close to the Juniata river, as well as a few of its small tributaries, so I often see some mayflies sticking to my screen door. This one in particular was there as a dun when I was leaving the house, and then as a spinner when I got back! It was a fairly large mayfly, just wondering if someone has a name for it. I'd say it was about a size 12, or possibly a little larger.

Just realized my wife is in the background of the spinner picture... I think she was saying something along the lines of "why are you taking a picture of a bug?"

Agreed. Slate Drake.

None of the above, give us an idea of where it was found.

I live pretty close to the Juniata river. Can't actually see the river from my place, but it's not that far - 1/4 mile maybe. There are also several small mountain streams that run into the river within about 1/4 to 1/2 mile of my apartment. I'm not right on any water at all - I think the flies just fly up here and I occasionally see them, so it's hard to say where this guy most likely came from.

Andy,

That's an old school name. Bust it out from time to time just to throw people off. LOL

I keep them in my box between the picket pinn and hornberg.

I know the Picket Pinn and the Hornberg! I'm using that name though!
