Hex Mayflies
Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

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.

What are you slackers doing now? It's been 2 hours since the last post in this thread -- get to work! And don't give me any of that "it's 3am, and I am safe and asleep" silliness, either. I can see on my clock plain as day that it's only 11pm!

I like the (Falsifly) olive hatch -- drad I missed that hatch too.:)

John

They fasten red (crimson red) wool around a hook, and fix onto the wool two feathers which grow under a cock’s wattles, and which in colour are like wax.

John, don't despair. The olive hatch is known to be multi-brooded, meaning that partaking of it can be a season-long affair. On the bountiful gin-clear flow that Falsifly plies, it may well be a year-round encounter. ;)

Gonzo- You have come up short on two points. Yes, it is multi-brooded but it is also multi-mooded. And, it is more than a year-round encounter it is a life-time endeavor.

Apparently the Fish in PA didn't think the BHO(bead headed Obama) looked good enough to eat. Seems the CCC(Cased Clinton Caddis) Worked better at least on the older rainbows and younger brookies. The Browns still liked the looks of the BHO. I guess something smelled a little fishy with Obama's line. I guess Clinton is a better imitator.

I wonder which one big mouth's would prefer.

By the way, Anyone have photo's of those patterns?

I have seen nothing more beautiful than the sunrise on a cold stream.

I don't think it would be a good idea for Mr. Obama to take up fly fishing. I'm worried if he does, the rest of the Windy City entourage will decide to follow suit. Then we'll have Rich Daley, Rod Blagoy..umm Rod Blagee..umm Rod Blagav...umm the Governor of Illinois, Gary Senise, Joan Cusack, R. Kelly and most worrisome of all, Mike Ditka all roaming around on our streams.

And somewhere along the lines, Ditka is all but certain to run into Joe Humphreys and that'll be like the asteroid Ceres colliding with the 3rd moon of Jupiter

I just don't think it would be good...

Scott, it's a wise man who knows when to leave well enough alone--wish I had the knack.

Lee, I wouldn't worry about Mike Ditka...umm, Mike Dyzcko...umm, dat guy dat played wit da Bears. I hear he's busy entertaining at his restaurant, smoking cigars, drinking wine, and (once again) trying to redefine what it means to be a tight end.

Speaking of Ditka, here's a fun bit of trivia: When Obama's Republican opponent for U.S. senate got knocked out of the race by a scandal, and the Illinois Republicans were scrambling to find someone else to run against the new Dem superstar, they apparently asked Ditka to run and he turned them down.
