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.

Nice bamboo, Eric! What's the make?

This bug, captured and photographed by the long lost Lastchance, during the same hatch that Eric landed that beauty.
The males were more of a "traditional" Hendrickson/RedQuill color.

All men who fish may in turn be divided into two parts: those who fish for trout and those who don't. Trout fishermen are a race apart: they are a dedicated crew- indolent, improvident, and quietly mad.

I've seen the exact same thing, and have some stuck shucks in a dry box back home in that dark hue. I thought for a time, (like Art Flick had), that the males were the dark ones. And maybe more of them are. But, over time I've seen both dark and light versions emerging on the same stream at the same time. Sure they darken after emergence, but I think there may be more to it.
If invaria are of any comparison, I would not be surprised if subvaria showed great individual variablity too. Wish I had my journals with me bc it's been awhile but I made special note of the color variability I was seeing. I wondered at the time if the variability was an adaptation to fickle spring weather, giving dark individuals an advantage over light ones during cold snaps. I've had enough times when I've had Hennies popping and nary a fish up to meet them. I also wondered if males were more apt to be dark and that there was some skew toward darkness in males.
But I trust my observations only so far: I have no stats, and I have no good handle on how comparatively recently emerged they all were.

Those two look like they are having way too much fun! I think they told the wives they were at the office...It's written all over their faces.

It happens to the best of us...
Tho' much is taken, much abides; and tho'
We are not now that strength which in old days
Moved earth and heaven; that which we are, we are;
One equal temper of heroic hearts,
Made weak by time and fate, but strong in will
To strive, to seek, to find, and not yield.
Tennyson's "Ulysses"
