Some sort of Hex?

My mayfly id skills aren't where they should be, but is this some sort of hex? I have about a million of them on my porch right now.

How big is the bug and what waterway do you live near?

 

[mario66pens]

sz 4 maybe 6 and on a tributary of the juniata about a mile above the mouth.

Probably a Hex.

If you Google "Hexagenia spinner Troutnut" a bunch of photos come up from Troutnutcom's website.

Looks like one of the hex species to me

Male hex spinner is my guess. Females are bigger and lighter if I'm not mistaken.

Image doesn't show for me.

Hexagenia atrocaudata would fit time wise.

Limbata is typically early Junish, with rigida and bilineata in July, and atrocaudata bringing up the rear in August.
