my first snipe fly, this one has a ragged wing, a bird encounter? In woods by a small lake
No interactions present.
The only concern for me with tringarius is that the humeri are not obviously yellow, as they normally are. Otherwise, it looks right. I don't have any experience of the rare R. annulatus.

It's hard to be absolutely certain without seeing the palps or front coxa, but the yellow scutellum, although not conclusive, and generally paler appearance, leads me to think that tringarius is much the most likely name for this one. Also what can be seen of the hairs on the abdomen in the third picture look more black than white.
I have specimens of tringarius with dark humeri, so that's not 100% reliable on its own.
