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

Two major forks of this grayling stream come together in this pretty pool.

Ephemerella mucronata Mayfly Nymph Ephemerella mucronata Mayfly Nymph

Dorsal view of a Ephemerella mucronata (Ephemerellidae) Mayfly Nymph from the Yakima River in Washington

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.

Oldredbarn has attached these 5 pictures. The message is below.

1995 Madison River 23.5" Brown. Eric Swedman & Spence

1995 Eric Shores with Spence's torpedo Brown...Who loves wild trout?!

Why do we all have one of these shots? Rod in mouth? This shot was for the Michigan Fly Fishing Club because the Loomis rod there I won at my first club meeting after I had paid my dues.

Madison River Bow 1995...Took a size 16 Bill Monahan version of a Partridge Caddis...What a healthy specimen!

Yellowstone Park Elk...I'm on the opposite bank of a skinny raging little creek and I could not get him to lift his head for the shot. I'm jumping up and down shouting etc and finally! I bet he's happy I'm a vegetarian!

This is for Jesse and Matt...My contribution to the east/midwest vs Montana undercard...And in this corner...etc.

I have finally purchased a small Canon digital camera (Thanks Wiflyfisher!), but prior to now I had a Nikon F3 which, in comparrison is like carrying a frig around your neck...

Anyway, I'm heading up tomorrow to fish and I hope to play with my new camera a bit, when I'm not poking trout...

I am trying to add a couple pictures here from my trip out west in 1995. If this works there are two Eric's in the photos with me...Eric Swedman holding Mr Big. He's the manager of Madison River Fishing Co in Ennis...The other Eric holding that torpedo of a wild, healthy, Madison river Brown is Eric Shores and he guides out of MRFC.

I'm geeked about heading up and I'm trying to calm myself down a bit, but these photos aren't helping...

See you in a week or so!

Hahah Spence bud thats freaking awsome and those pictures just really help to distinguish the diversity in fishing eastern vs. western waters. The fish are beautiful, the scenery, the wildlife...its all just absolutely breathtaking. Sorry it's taken me so long to get back to you buddy ive just been so busy getting back home, trying to make some money, and then figuring out plans for an already near future for going back to Montana. I haven't had that much time to get on and check things out, but it's always good to come back to some pictures like these ones. Your bug shots were great too so no need to be modest about it aha! Good day to you buddy ill be checking more often now!

Most of us fish our whole lives..not knowing its not the fish that we are after.
