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.

As far as I can tell, this species has only previously been reported from one site in Oregon along the Columbia gorge. However, the key characteristics are fairly unmistakable in all except for one minor detail:
— 4 small yellow spots on frons visible in photos
— Narrow occipital spinule row curves forward (but doesn’t quite meet on stem of ecdysial suture, as it's supposed to in this species)
— Short spinules on anterior margin of front legs
— Short rposterior row of blunt spinules on abdominal tergae, rather than elongated spinules dorsally
I caught several of these mature nymphs in the fishless, tiny headwaters of a creek high in the Wenatchee Mountains.
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'm from Eastern Missouri of all places, I like to fish for trout in the streams of the Southern Missouri Ozarks. I'm headed down to the Current tommorrow, will give a fishing report. Just wanted to say hello. I help run a fishing website, which I won't link to until I've actually contributed something useful on the forum LOL.

Welcome to the site, you'll find friendly folks here who love to fish and talk bugs.

You MO guys are giving me the fits - I guess I just need to go on a fishing vacation down there sometime! Some old stomping grounds...

Jonathon

P.S. Mudshack, be sure to check out the Blue River south of KC for largemouth, panfish (including white crappie), and channel cats (I actually managed to catch a couple of them on FLIES a few years ago in TX). GOOD LUCK!!!
No matter how big the one you just caught is, there's always a bigger one out there somewhere...

Yeh, the Blue is pretty and has a ton of deer around it. Channel cats.....hmmm....never thought of that. I figured it was a chub, sucker and rockbass stream.

How did that Ozark fishing trip turn out?

I grew up in northeastern Missouri, in Kirksville. I'm very glad to have lived in troutier places since I moved away from there!

Mudshack, I did pop a 16" largemouth in the Blue on a little (#10) silver minnow imitation once. It was nothing more than some silver Mylar braided tubing and a pair of small silver dumbell eyes, but as soon as it hit the water that fat boy swam up to it and sucked it in, before I could even begin to strip it. YEE HAW!!

P.S. I don't remember ever pulling any rock bass out of there (many more down south with the smallies), however I did get some nice bluegill, green sunfish, and white crappie. There are also CARP if you are inclined to chase them (I am not).

Troutnut, the trip that weekend turned out pretty good... The fish were rising to caddis, which made for a pretty nice day.
