Pteronarcys californica

The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

I was not fishing, but happened to be at an unrelated social event on a hill above this tiny creek (which I never even saw) when this stonefly flew by me. I assume it came from there. Some key characteristics are tricky to follow, but process of elimination ultimately led me to Sweltsa borealis. It is reassuringly similar to this specimen posted by Bob Newell years ago. It is also so strikingly similar to this nymph from the same river system that I'm comfortable identifying that nymph from this adult. I was especially pleased with the closeup photo of four mites parasitizing this one.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

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.

Any ideas what they are?

Bruce - Looks like some kind of Crane Fly. Here's one from Bugguide.

Thanks Millcreek!

I have never seen Crane Flies that small or so numerous.
