The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.

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.
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.

Wondering if someone could help me with a pattern I am trying to replicate. I went to a fly tying demo at my local trout unlimited, took a lot of notes, and have been able to replicate all but one as it calls for tying in partridge under-feathers towards the eye, which I have never done before. Basically, the fly is tied on a scud hook with green thread, a few strands of a mallard feather for a tail, and then I wrote "tie in partridge secondary feathers towards eye" and have no idea what I had been intending... any ideas? I tried tying in the secondary feathers like a typical hackle wing, but the shaft of the feather is too thick and bulky. Would greatly appreciate your help if you have any experience with using these feathers.

Well, your notes could mean a number of things. If this was caddis pupal pattern, sections of the secondary flight feather on the wing could have been tied in as under developed wings like these:

It is also possible the tier meant secondary under-coverts from the wing tied as hackle rather than wings. Under coverts were often used on soft-hackle wets as a hackle.

I'd suggest next time do a little sketch of the fly.

Can you get in touch with the tier?

Thanks, Mark. I was able to make contact with the tier yesterday and was able to get some help, but still trying to picture how it will look. I'll try out some possibilities tonight. The tier confirmed that it is an olive soft hackle emerger where he ties on the secondary feather about 2 eye-lengths from the eye, wraps it once or twice and then whip finishes. Simple as that. I'll let you know how it goes.
