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.

My brother noticed a large swarm of flying insects all around his house over the Thanksgiving weekend. He lives in northern Indiana. They would fly around and land in the grass.
They look like chironomids to me although the wings are not long and thin and don't rest horizontally folded over the back. There's a small pond across the street.
