I’ve been running into swarms if these on a well know Westmoreland County stream.

Generally, I would this is the time of year you will start seeing March Browns showing up across PA. Closely related, if not the same species are the Grey Foxes. I think the same species, but a little different coloring and size.

There is some discussion here -

March Brown - Maccaffertium vicarium

This was one I came across on Kettle Creek on April 27, 2010 at about 3:00 pm. Again size #14 or even maybe a #12. It was a cool and sunny day. Common Name: March Brown Latin: Maccaffertium vicarium Hatches Late morning - evening, early May - late May Tails: 2 Fore wing: molted Hind...

Yeah gray fox and march brown are the same species. Just a fair color variation within the species.
