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.

I was just wondering if anyone out there may have a favorite pattern that they could share for Pentagenia robusta? We all know that Spence could use some more flies to jam in his already overcrowded vest...One never knows when this might come in handy! I want to be prepared next time up. Make sure I have everything covered.

Thanks!

Why Spence, you did not specify what type of pattern. Is this to be a:

Nymph?
Wet fly?
Emerger?
Dun? or
Spinner?

Be sure you tie each in at least three sizes so you are truly prepared, and to pack a hip flask of your favorite alcoholic beverage to take the ache out of your back from yet another fly box...

;oD

So you have something then??? Holding back are you? I'll take whatever you have. Hell...Maybe Mark has a softhackle to cover it...I'll take that too.

Matt-

Yes, it appears our buddy Spence has been pulling our collective leg.

Busted! Damn Matt...Someone has to get up pretty damn early to get something by you, mister! ;)

Beside poking a little fun, as Roger points out, Jonathan was pretty close to figuring out the real pun, or problem...Its Spence...What does a notorious match-the-hatcher do?! Yes the bug seems to be no longer with us, but what if...(?) With all the weight in my vest how would I ever be able to face the boys back at the Lodge if by chance they did reappear and I didn't have them covered?!

Why Spence, you would pull out the Little Grey Bastard and do the best you could! Like Jonathon does with a Female Adams...Naaaaw, that's too easy for you! You'd have to capture a natural by the streamside and pull out your travel tying kit and set up on a picnic table...don't you keep that kit in your vest TOO in case of a previously unknown hatch?? Ah-ha, I see an innovative fly fishing accessory ready to be marketed - the ultralight vise you can carry in your fly vest and clamp on anywhere!!! I'd better get some drawings made up quick and run to the U.S. Patent Office...

Kurt,

When we were little guys my aunt Gwen would sit me down at one end of the coach, cousin Arlie at the other end, and cousin Darel in the chair..."You hoolagins(sp?) can sit here until you can learn how to play with each other without someone crying, bleeding, or needing a ride to a hospital...":)

We are lucky we escaped our boyhood with just the few stitches we received here and there, Arlie's dislocated shoulder, and my front teeth being capped...Boys! We did have some fun!

When they moved up north near Luther and the Pine River and the head waters of the Little Manistee we thought we had died and gone to heaven! Uncle Dee would drop us boys off at some small stream somewhere and leave us for hours...We would splash and wet wade right down the middle of the creek and wonder why we never caught a trout! Hmmm...

When we still get together at reunions or when Arlie & I are at the Joe together the fun hasn't stopped...It's just less physical now...Only feelings getting hurt.

I'll behave myself...Promise. On the serious side, there is so much going on here on this site that interests me and so much here one can learn to have someone playing games and distracting us...I thought this had the potential to be funny, but Matt is a good philosopher and "doubts" everything until he can prove it's true...Good work there Matt...I could just hear him say to himself, "Now wait just a minute here! What you up to bud?!"

To match extinct species, I like an invivible Borcher's parachute....

Tim... I guess you and I would be the only ones who could find the only fly tyer out there capable of tying an invisible Borcher's to cover an extinct May fly, eh!? That old irasible buddy of yours J.R. from Grayling...Probably even tell us the history of the thing and just where and how to fish it! :)

I was thinking about old Bill Kornecke (sp?) the other day...Remember him? Now there was Mr. Irasible! His is a story that somehow needs to be told someday! Someone needs to sneek him in to a short story or something.

When you talk to Jerry about this invisible fly order he probably won't do it unless we order a few dozen and I bet he could crank them out in a moment or two...You make sure you tell him I'm not looking for any of those "artsy-crafty" kind of flies...Just something, though invisible, will float and I won't have a hard time seeing it on the water...

(Livescience.com) After months of scouring remote forests in Borneo, researchers spotted three rainbow toads up a tree, snapping the first-ever photographs of this elusive amphibian species that hadn't been seen for 87 years, scientists announced July 13.


Last seen in 1924, the Bornean rainbow toad (Ansonia latidisca) had been listed as one of the world's top 10 most wanted lost frogs, or those that hadn't been seen in at least a decade.


Hmmm...Boys. Better get started on those flies to cover good old Pentagenia robusta...Anything with "robusta" in its name should be tuff enough to be still hanging around out there, somewhere, eh...(?) ;)
