This specimen resembled several others of around the same size and perhaps the same species, which were pretty common in my February sample from the upper Yakima. Unfortunately, I misplaced the specimen before I could get it under a microscope for a definitive ID.

I don't know if I'm in the right section of the Forum but I recently saw an awesome photo of an Ephemerella Dorothea dun emerging from the nymphal case. The dun's wings were dry and upright but the case was still attached, about half the body length, to the dun. Is that picture on this site and if so would anyone please tell me where it is. Thanks.
Sounds like you might be referring to the photo of a "stillborn" Ephemerella subvaria on this page, which appears at the bottom of the page in the Jargon section immediately above the definition for Stillborns.

Thanks for the info but no that is not the picture I saw. It shows the dun with the opaque gray wings and the sulfur color body and the big orange eyes. Then about half way down the abdomen of the dun you can see a brown nymphal case.
