Hex Mayflies
Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large Brown Trout that only touch streamers for the rest of the year.

Male Afghanurus inconspicua  Mayfly Dun
This pretty little dun was part of a sparse midsummer evening hatch on a large Catskill river.

I could not identify it by following a species key step by step, but I tentatively keyed it to the genus Nixe, and based on distribution maps and physical descriptions the most likely species is Nixe inconspicua.
Female Hexagenia limbata (Hex) Mayfly Spinner
I found this Hexagenia limbata spinner on a gas station in upstate New York, not a region known for heavy hatches of this species.
