Posts: 19This looks to be either Hexagenia or Litobrancha based upon the frontal process being rounded and not forked. Probably is Hexagenia based upon where it was collected and Hexagenia being so widespread and common, but I cannot tell from the photo if the gill on the first abdominal segment is forked or single from these photos.

You're right. I can't see how I would possibly have misidentified this one, so I must have just absent-mindedly clicked it into the wrong category when I added it to the site.
