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 Cinygmula (Dark Red Quills) Mayfly Spinner
I'm unsure of the ID on this one; keys put it closest to Cinygmula reticulata, but I'm very doubtful of the species and not positive on the genus. Epeorus is another possibility, but I don't know which species it would be.

This one was collected in association with a female dun probably of a different family.
Female Ephemerellidae (Hendricksons, Sulphurs, PMDs, BWOs) Mayfly Dun
This one was collected in association with a male spinner, but they appear to be different families.
