I'm fairly confident calling this dun Ephemerella tibialis because it emerged from one of several similar nymphs in my bucket, which I was able to ID with quite a bit of certainty. However, it looks very different from the other duns I currently have listed, which makes me rethink their IDs.
This mayfly was collected from the East Fork Big Lost River on August 3rd, 2020 and added to Troutnut.com on August 18th, 2020.
