ID this Bug

This picture is from a Facebook group called Pennsylvania brookie chasers. It’s from Pa in the last couple of weeks. I guessed Sulfur but another member noticed the 2 tails. The only thing that I know about entomology is that I’m glad I skipped that course in college.

But I could easily be wrong

A big generic Yellow Mayfly pattern would catch most fish feeding on it.

The two-tailed Pa mayfly in the family Heptageniidae of which I am aware is in the genus Eporus. It is very sensitive to pollution.

I agree on family but genus more likely a cahill type such as Stenacron especially if emergence was late in the day toward dusk. Sure is nice to have a big, bright wing to track if they are feeding on them

You’re right, as upon further research brought on by your comment I found that the Eporus nymphs that I am to seeing most likely become Quill Gordons.
