The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

This is an interesting one. Following the keys in Merritt R.W., Cummins, K.W., and Berg, M.B. (2019) and Jacobus et al. (2014), it keys clearly to Ephemerella. Jacobus et al provide a key to species, but some of the characteristics are tricky to interpret without illustrations. If I didn't make any mistakes, this one keys to Ephemerella mucronata, which has not previously been reported any closer to here than Montana and Alberta. The main character seems to fit well: "Abdominal terga with prominent, paired, subparallel, spiculate ridges." Several illustrations or descriptions of this holarctic species from the US and Europe seem to match, including the body length, tarsal claws and denticles, labial palp, and gill shapes. These sources include including Richard Allen's original description of this species in North America under the now-defunct name E. moffatae in Allen RK (1977) and the figures in this description of the species in Italy.

Just curious. What do you use for sulphur spinner wings? I've been using light dun poly.

I like hackle spinners. I use oversize hackle and tie either a parachute or a wrapped hackle wing and cut it off on the bottom (and sometimes on the top). I also use snowshoe and CDC on smaller spinners. I've seen Webwing spinners that work very well also, but I haven't tried them myself. Yet.

Honey Dun rooster hackle.

I have been tying some flies from S. Nemes "Spinners" book. They look wonderful and he uses either rooster or hen...I haven't tried them yet...Will give a report in a few weeks. They look very realistic to me and therefore may be difficult to see with my 56 year old eyes, but I'll let you know. They float flush in the film.

The interesting thing Nemes did in this book was to mic the abdomens on different spinners and he concludes we are tying fat bugs for the most part. He found some that are not that much thicker than the hook shank...He ties them with just tying thread and fine gold wire.

Parachute style flies work well to imitate a spinners profile or silhouette and are easy to follow on the water.

I'm rather fond of a spinner I tie based on a fly by Datus Proper. In his, "What the Trout Said", he uses a literary device where he claims to have conversations with trout in different places where he's fished. After the results I've had when fishing his ideas I'm not too sure it was just a device. Some guy named Vincent Marinaro was rather fond of Mr. Proper as well.

Hackle wing spinners, where you figure 8 the fur thorax around and under the hackle are beautiful. I used to think they had an edge over poly, or other synthetic, wing material. They are much harder (for me) to tie than synthetic wing spinners and take longer to tie. Some of the rivers I fish out west have phenomenal spinner falls and I've been able to compare hackle wing effectivity with synthetic wing. I seldom see any difference in fish catching ability for the average trout that is feeding heavily, especially if other trout are competing. However I have seen situations where there may be a single lunker, feeding tight up against the bank, where the delicacy of the hackle wing spinner seems to have an edge. So while most of my spinners are tied with synthetic wing material I still tie a few, of certain pattern, with stiff hackle.

TNEAL: You're speaking of spent wing spinners, right? Do you have pictures of the method you use to tie in the wings? It sounds better than how I do it. Also, as far as fat bodies, I think Nemes is correct. It's probably best to tie thread bodies or biot bodies.

Yes, spent wing spinners. Interesting you mentioned that... often overlooked is the fact that lots of spinners hit the water before dying and have their wings in various positions..... Sorry, no photos... put the wings on top of each other with wing tips exactly even... make first thread wrap where you want the wings to extend outward from... several more wraps to the rear will secure them... take thread back to original position.... pull one wing toward you and take one or two wraps to hold it in place; repeat with the other wing... quick and accurate spent wings... the best method by far that I've found... started doing it 28 years ago after having been shown this method by Clarence Roberts, our old conservation officer and well-known area tyer.. he originated one pattern in particular that is among the best parachutes patterns ever

Many of my spinners are tied with hackle, para-style around a 6x mono loop, then the loop pulled down over eye and tied off. Then wet and stoke the fibers to gather. Wind back....tie in tail, dub, whip finish. They are as indestructable as poly wings, and more transleucent.

My problem with fishing any spent wing spinner is seeing the thing on the water. I'm OK with tricos due to the time of day the fall happens. Throw low light into teh mix and it becomes a real challenge. For this reason I tend to favor a parachute with a short post and wedge trimmed out of the hackle both fore and aft to give the impression of the spent wing silhouette.

Another option is to drop a soft hackle off the bend of a more visible dry fly. If you slightly grease the wet fly it will stay in the film and you have a ready made indicator in the dry.

Pm10,
The hackle stacker style you speak of is also a good one.

During a good spinner fall you don't need to see the fly as much as you need to know the general location. I fish mine blind under the surface, and will occasionally throw on a big Green Drake just for an index. In many cases the Green Drakes and PMD's coincide so sometimes they draw strikes as well. But with a good spinner fall the water is boiling so I say if you see a rise in the general direction, its either you, or its worth the effort because you're probably landing a fish in the next case anyways.

I tie mine with poly yarn and I think the most important features are the profile and color so I really focus on getting that tail spent, the wings flat, and the color nice and rusty.
...but fishermen I have noticed, they don't care if I'm rich or poor, wearing robes or waders, all they care about is the fish, the river, and the game we play. For fishermen, the only virtues are patience, tolerance, and humility. I like this.

I usually go to a Galloup's Cripple with hackle wings & one white hi-vis wing, with a red quill or brown biot body. Natural fallen spinners are rarely splayed out in the idealistic spread-eagle position, and I find that this cripple pattern represents the real fallen spinners (bodies twisted in various ways, often just one wing flat on the water, etc) very well. I use this pattern a lot, including for duns or as a general attractor. It's probably my favorite hard-to-see dry fly because it works so well on otherwise finicky trout. (My favorite dry flies are big, bright, bushy things that float like a cork and are easy to see, but I only fish them when they work, which they do less often than a Galloup's Cripple.)

When I do want to fish a spread-eagle spinner instead, I get really fancy and tie three lumps of hi-vis across the thorax, then trim them to a perfect mayfly wing shape with special wing burners I cut myself. They take a long time to tie and can be annoying with the line twist, but they look so cool!

Best winging I've used in a long time, for small flies like PMD's, BWO's for dun wings, or spinner wings are EP fiber sold in a long skein. Just cut off the length needed, can be trimmed after, takes floatant. I use grey fibers.
But this year we had an exceptional Grey Drake fall because of our very high water (Grey Drake fall on the Henry's Fork of the Snake) and a parachute Adams in a size #12-14 worked exceptional at matching the spinners.
