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.

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.

Wbranch has attached these 3 pictures. The message is below.
The huge box on the far left is a boat box and is unique in that it can be closed and inverted and there is another two page box identical to this side - equally full of Clousers. The two silver Wheatley's are steelhead flies in the box in the middle of the frame and Atlantic salmon flies in the box to the left.  The box to the immediate right of the center Wheatley are also all hairwing steelhead flies but smaller #6 - #10.  In the two large clear boxes in the foreground are back-up stock of bonefish and crab flies and the box to the right are all Atlantic salmon dry flies.

There are a minimum of 7000 flies in the boxes, probably more than 8000 - but who's counting? HeHe!
The other one third of my fly boxes - the long green box is all shrimp & crab patterns for bonefish and permit. The large opague gray box on the upper left is big striper and shark flies as well as barracuda flies and big poppers and I can see about a dozen grasshoppers too.
A close-up of four of my six C&F boxes. The two boxes in the upper row are various PMD emergers, duns, and spinners and also a gazillion cinnamon CDC caddis adults, pupa, and spent caddis.  THe bottom left hand box is all Ep dorothea (Sulfur) emergers, duns, and spinners in #18 - #22.  There is a Myran box for the #16 duns and emergers and a larger 4" x 6" box for Ep invaria #14.  I've got my boxes set-up to be hatch specific.  Separate boxes for every hatch that I encounter on the Delaware system and the Montana tailwaters and spring creeks.

Sorry for posting my picture here relative to the "Fly Boxes" thread but when I post in the regular forum my pictures come up thumbnail size and don't enlarge when you click on them. This is most of my fly boxes although I know there are two boxes of Clouser minnows and one box of Sucker spawn, Glo-bugs, and Blood dots down in my closet in the garage but was just too lazy to go get them.

You better start tying, buddy, it looks like your short a few flies for the new year. Ha! Ha!
I know how they add up for sure. My boxes would cover a queen size bed.

PS. Don't your dry fly hackels get matted in those C & F style boxes?

Bruce,

"PS. Don't your dry fly hackels get matted in those C & F style boxes?"

No, because I never put winged dries in the swing leaf page and all the dries in the front and rear, deeper, covers are no larger than #16 and most are #18 - #22.

I just hate it when I smash delicate CDC or turkey flat wings or bend nicely split microfibbet tails. I never crowd the flies into the compartments of the Dewitt boxes. I try and nor put more than 6 - 8 #14's and less as the hook size gets bigger.

Damn Matt! I'm not so surprised about the number of flies there, but you are so organized! I am impressed sir...I could use a little of that in my fly tying life. Ok I could use alot.

Yep, I'm very fastidious about the appearance of all my boxes and especially the C&F boxes. Two reasons; when friends are around and I open it they always anxious to grab the boxes out of my hands and oogle all my handiwork and admittedly I get pleasure from that. The other reason being since the very design of the rows and slits lends itself to at least some organization I can load the boxes hatch specific and by life cycle stage. Say 3 rows for nymphs, 4 rows for emergers, 4 rows for duns, and 3 rows for spinners. Then as I expend flies I'll see what empty slits need to be re-filled. I also just enjoy organizing the boxes over the winter when I'm not fishing.

When asked what I just caught that monster on I showed him. He put on his magnifiers and said, "I can't believe they can see that."

Yes, I was a closet fly freak but now I've come out and you all know the truth of my afflictions!

Matt, your level of organization AND productivity are both impressive! Looks like you are ready for anything and everything! Truth be known, I'm on the opposite end of the spectrum - I work out of maybe 6-8 fly boxes during any given year. But, they are all flies that work for my local conditions and I don't have the income to do much travelling these days. I assume that every box in there has found some use to you on some day within the past few years...or are you just padding your collection to impress us?

;oD

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