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.
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.

do any of you mess around with articulated type streamers?
If so what techniques do you use/ style of articulated streamer do you like?

One I'll be tying this year is the "Sex Dungeon". I'll use heavy mono to connect the rear fly with beads.

I've had success with the Galloup-style articulated streamers, esp. the Heifer Groomer (a hinged Zoo Cougar for all intents and purposes) and the Sex Dungeon. I use Beadolon stranded for the 'hinge' with the obligatory bead(s) in red, gold, or silver depending on a whim I guess.

Sidebar, I've had the most hookups with these streamers on BIG water such as the Muskegon and Lower Big Manistee- I don't even bother to bring them to the smaller streams I intend to fish.

There's a love/hate thing with articulated streamers...I like to tie and throw them, other anglers I've fished with consider these flies anathema.

Hey John,
I've tied and fished them, but I don't really fish streamers enough to give a good opinion. It did occur to me that I might do just as well for trout with buggers. Roguerat made a good point about having more hookups on large water with them. I do catch a lot more bass with articulated streamers on larger water like the Juniata and Susquehanna.
