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.

I caught this tiny larva without a case, but it seems to key pretty clearly to to Glossosomatidae. From there, the lack of sclerites on the mesonotum points to either Glossosoma or Anagapetus. Although it's difficult to see in a 2D image from the microscope, it's pretty clear in the live 3D view that the pronotum is only excised about 1/3 of its length to accommodate the forecoxa, not 2/3, which points to Glossosoma at Couplet 5 of the Key to Genera of Glossosomatidae Larvae.

Color. Doesn't the underside of these nymphs appear brown/olive? I'm talking, Hendricksons, Sulfurs, Cahills, March Browns, etc. Am I correct? Please don't hesitate to set me straight.

Bruce,
They run the gamut in the bottom huggers (crawlers & clingers). Imatures are often pale creams, tans, browns & grays underneath. As they "ripen", the undersides tend to take on the colors of the duns only usually exaggerated (more intense). The most common ones I run into turn yellow, orange, tan, and greenish olive.

Eric...All I'll say is you started it...:)
Variation...I'm in a Vinny state of mind...
p 100, "There is a further limitation in the sobering and distasteful fact, easily observed, that there is no true uniformity of color in a given hatch of one species of mayfly. Let anyone try to establish for himself the correct color of the natural by examining and comparing not one, but many of the individuals of a single species during the hatch, and he will discover a variation so marked, in some cases, that he will forever despair of coming to a definite conclusion."
They were fairly bright way back in 1950...

Oh no, you've just given Spence an excuse to tie three more boxes worth...you might want to send him some Vicodan for his back!

No matter how big the one you just caught is, there's always a bigger one out there somewhere...

Jonathon...
They are all tied up here over the last week or so, except for the spinners...:)
I have some old friends coming over tomorrow night so I had to try and make the basement presentable...What a job! It was a mess...I've been on a tying tear of late...
I'm taking a little break from cleaning before heading up to bed and just found a Starling feather stuck to my slipper...:)

That's better than finding the whole bird

I actually haven't tied anything since probably September or so. Well, it's about time to start again, maybe some fresh steelhead flies like Egg-Sucking Leeches since I'm actually contemplating that again this year. Once I get a fly rod in my hands again the urge will be automatic.
