birkinDescription
I'm guessing that it is a member of the Little Stout Crawler Mayflies, based on my Voshell text: "In top view, the only structures that are visible on the abdomen other than the tails are a pair of large, thick, movable plates. The plate-like gill protectors are shaped nearly like triangles, and there is a space between them in the middle."
