Blue-winged Olives
Baetis
Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.
Featured on the forum
This dun emerged from a mature nymph on my desk. Unfortunately its wings didn't perfectly dry out.
Troutnut is a project started in 2003 by salmonid ecologist Jason "Troutnut" Neuswanger to help anglers and
fly tyers unabashedly embrace the entomological side of the sport. Learn more about Troutnut or

Looks more like Strophopteryx fasciata (Mottled Willowfly, aka Little February Red) to me, Eric.

Yours is a male, BTW.
Both are reported from PA and look very similar, but the unique muted banding on the wings is what tipped me off. Here's a good photo of Taeniopteryx parvula (Hooked Willowfly) for comparison. http://bugguide.net/node/view/260929#397606

Strophopteryx fasciata (Mottled Willowfly, aka Little February Red)
When did this happen? While I was asleep :)...What happened to Brachyptera fasciata?
I'm going to have to try and stop hassling the trout for a moment and take some pictures this season...I'm having a small problem with the available hatch charts as well...I have a bug in late May that looks a great deal like this one with the orange trim. Most of the charts have it done by early May???

Collected this one yesterday on my way home

Looks like another Strophopteryx fasciata, only a darker because of the light in the photo, Erik.

:) Well, you've put Rip Van Winkle to shame on this one. Brachyptera is a genus name in the old classification system established by Stanley Jewitt back when dinosaurs roamed the earth. In 1977, R.W. Bauman, et.al. introduced a new classification system that is now the standard, though revisions that give mayfly workers a run for their money are constantly ongoing.:)
Brachyptera is now an obsolete name, though its taxonomic history is recognized in the current subfamily name, Brachypterinae. All the species were moved to newly named genera.
Under the old Jewitt system, all the little early dark stones were in the same family, Nemouridae. The new system has them broken up into four families. Nemouridae has retained its family status, but most of the important genera have been moved to others, analogous to what happened to the mayfly genus Stenonema.

Yeah i thought so too interesting how much darker this one is not as much of the brownish orange. There are three threads going on these critters right now I'm getting confused.

Yeah, we should probably reserve our conversations about what is going on for the "confused" topic and just stick to determinations on the others.

"confused"
Kurt...This might apply to most of our threads most of the time...:)
Rip Van...:) Well there is a Van in my last name...;) I think that the old hatch charts around these parts need some serious updating! I remember an old cabin I would stay in from time-to-time had an old one screwed to the wall and we would laugh about how outdated that one was...Maybe its time for a house cleaning!
Maybe if we could get Jason back down here in the Lower 48 and warm up that camera of his we could fill in some holes and lock this up...

Ha! Even if we could get a hundred Jasons coordinated, they'd never get the job done. The biodiversity on this continent is astounding. I agree they'd put a pretty good dent in it, though. The problem then would be we'd have a hundred more guys arguing over what to call them!:)

Kurt,
Maybe we could get him to come to Michigan and help me out a bit...:) We got to start somewhere. Might as well be the great state of Michigan...

Well, get him a job at Michigan!:) It's a lot closer to good fishing than that other university in East Lansing. My sense is with that degree of his, he'll end up on the West Coast though.

We may have to send you a good map Kurt...:) East Lansing's technically "closer" to the Holy Water and "up north" than Ann Arbor which is 45 mins west of Detroit.
I spent this evening, by-the-way, in Ann Arbor with my wife, my step-sister, and her daughter...They are visiting from Hawaii and I wanted to show my niece, who just graduated from high school, a place her uncle would like to see her study...Hawaii unfortunately is hard to beat.
After a tour of the town, dinner, and a nice blue-grass concert I think she was way more pleased with having had spent the time with her uncle than marveling at the Harvard of the midwest. :)
Now Jason, on-the-other-hand, might fall for my wine-and-dine...:)
