Konchu & Taxon... small, green-eye mayfly dun, 1/4" long body length. What is it?

okay Thank you!

Leucrocuta hebe (Little Yellow Quill). Although it looks darker than the one's Jason has on the web site, but probably from the same trout stream.

Konchu nailed it, for sure, but Iíll try to contribute something by posting one of Jasonís photos to which you referred, when you mentioned that yours was darker, but probably from the same trout stream.

Wisconsin has two species of Leucrocuta, L. hebe, and L. maculipennis, and based on their respective descriptions, it could be either. Both are referred to in earlier literature by genus name Heptagenia.

This is timely, I saw one of these today. It floated down to me, dead?? on a small spring creek.

The species IDs in this genus are tough now. Some of the names aren't tied down real well to morphotypes. So be careful...

Wiflyfisher, did you save the specimen you photographed?

Yes, I saved it but it is all dried up and I don't remember which small sample bug box I put him in. ;)

Heptagenia mayflies I have seen over the years on this same river were a more pale yellow. I might have mistaken it for something else now that I see Jason's photos.
