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.

I was not fishing, but happened to be at an unrelated social event on a hill above this tiny creek (which I never even saw) when this stonefly flew by me. I assume it came from there. Some key characteristics are tricky to follow, but process of elimination ultimately led me to Sweltsa borealis. It is reassuringly similar to this specimen posted by Bob Newell years ago. It is also so strikingly similar to this nymph from the same river system that I'm comfortable identifying that nymph from this adult. I was especially pleased with the closeup photo of four mites parasitizing this one.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

By Troutnut on July 9th, 2011
It's been a busy year, and this is the first time I've been out fly fishing. My wife and I drove up to Nome Creek for a couple hours, looking for some easy action on small grayling, and it did not disappoint. I was still threading the line up through my guides when I heard her calling from the stream with a grayling on her fly. I told her that since she got the first fly-caught fish of the year, she can officially wear her I outfish my husband! merchandise now.



I also collected some nymphs for the site for the first time in a few years, including several mature Ephemerella aurivillii nymphs. Our dog Taiga had not experienced kick-netting before, but she decided to try to be as helpful as she could, imitating me by walking in front of the net and pawing at the water. The collection was very successful.

This is the first time I've kicknetted bugs since we got Taiga, and she turns out to be so very helpful.

Very nice. Such nice images attached to a fishing report/slice of life are truly wonderful. Nice to know others are out there even if I'm stuck in domesticity.

Jason,

Your bug there looks like a bleached or faded "Henny"...I think we could cover that one without a problem.

Love that Grayling...I've said here before that the only Grayling left in Grayling, MI is hanging on the wall at the Grayling Restaurant...I dream of fishing to them one day!

That's a pretty looking stream!

Spence

I'm also a little envious watching how little you are carrying there Jason...They used to say that the Grayling here wasn't such a "smart" fish and they would sometimes catch multiple fish at the same time on tandum rigs...Besides everything else they had to endure here this trait probably didn't work in their favor in the long run.

That really looks alot like a Hendrickson or should I say, a Red Quill. Is there a common name?

BEE-YOO-TEE-FULL photos, Jason, both large and small. And way to show Spence how us "minimalists" do it before he requires some serious back surgery for carrying the load of two vests in one...

As far as Grayling, Michigan is concerned, I always refer to it as "the town named after the fish that it killed"...Kinda like streets named after the trees that used to grow there before they were all cut down for subdivisions and strip malls.

I'm envious that you have a fishing wife...and is that there dog helping kick up bugs off the bottom?

I just added pictures of 6 more bugs (7 specimens -- one was added separately as a nymph and dun). Now we know what both genders of Ephemerella aurivillii look like as duns.

Anyone know how to identify western Cinygmula (nymph & corresponding female dun) or Heptagenia (nymph) species?

I've never heard of a common name for Ephemerella aurivillii, but it should probably have one considering how widespread it is.

Jason -

One thing that strikes me as very interesting is both sexes have little color difference between their dorsal and ventral surfaces.

As to a common name? As probably the first photo's of duns associated with the nymphs taken Jason, the honor goes to you to get it started.

Whether we like it or not though, I think it's going to end up being lumped with the Hendricksons much like the small Western sulphurish ephemerellids are lumped with PMD's and the Eastern olivaceous ones are lumped with the BWO's. Perhaps get a jump on it and put an appropriate word in front of Hendrickson?

You can certainly see why this fly was never differentiated in the East. No excuse for us out West though. Rumors of large pinkish ephemerellids have persisted for years, and a few brave souls have even described them in print with the caveat that it must be the soil or water chemistry "that done it". Peer pressure is a funny thing. We're not supposed to have "Hendricksons" out West according to orthodoxy so these reports usually get chalked up to mistaking Epeorus albertae (Pink Gordon) inspite of the different tail count.

This is a very interesting turn of events.

Regards,

Kurt

I'm not sure what would be a good common name for them. False Hendrickson, maybe? My first thought was "Little Western Hendrickson," but I don't really like those long compound common names that appear in books but nowhere else, and it's not just a western species anyway. Since it's a circumpolar mayfly, maybe it should be called the Magellan. Or, since the duns eluded public description for so long, they could be called Ninjas. Or, as you suggested, Bigfoot. Since I already have Darth Vaders and Booger Sulphurs on this site, it can't get a whole lot stranger. Here are a few more ideas...


  • Lipstick Sulphur
  • I Can't Believe it's not a Hendrickson!
  • Redandorolive Quill
  • Blue-Winged Olive (Why not? People call everything else that!)


I guess I'm kind of partial to the Latin name for this one. It's a fun one to say. It'll twist your tongue once or twice but then it really rolls off, assuming I'm pronouncing it correctly anyway: aura-villy-eye.

My guess would be aur-uh-VILL-ee-eye.

What about calling it a Villy? Or, a Villy Hendrickson?

BTW, how do you bug guys tell the diff between the Villy and the Subvaria or, true Hendrickson (ha! ha!)

Taste really! The Villy goes better with a Pinot and a slice of asiago while the good-old-fashioned Henny is better with an ever so slightly chilled Merlot...

And what type of bread would you recommend, Spence? A nice sourdough, lightly toasted, or something more along the lines of a rye variety, perhaps with caraway seeds, hmmm? Or maybe a chunk of focaccia dipped in herbed olive oil...must be getting near my lunchtime!

Uh-oh, we're turning into the Food Channel again...

My vote is to NOT give it a common name.

How about Hellegravilly. If it catches on then someone in the future can puzzle over the name.

All I ask is please, PLEASE, not a bastardization of it's scientific name! Flav's, Trico's. Lepto's, Hexes... Drives me nuts!:) How about Pale or Pink Hendrickson? You could throw a Western in there Jason, it's not that painful.:)

A play on it's name would be ok though. How about "Village Idiot"? Describing (encounters with) pink ephemerellids out West has unfairly caused a few anglers to be thought of that way in the past.:)

Better be careful here Kurt or Roger's going to think you and I have been out drinking together...Your tongue is in a cheek-like position in a Spencer-est fashion...;)
