The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
Don't think so, at least about Brachycercus... Slim Baetid bodies, two tails, spurred hindwings.
Jason probably misspoke himself, and actually meant to say Brachycercus (the mayfly) rather than Brachycentrus (the caddisfly).
Anyway, you really lost me when you said:

Aren't you actually describing Centroptilum rather than Brachycercus? Just asking :-)
Though the generic name has not been done away with, most species of possible importance to fishermen have been scattered among several genera (at least for now) where this unique wing feature is not shared, thus making stream side identification beyond the familial impossible.
"These very small mayflies usually inhabit slow or still water and might be of local importance to fly fishers in some cold lakes, calmer sections of some spring creeks, or cold brooks in beaver pond meadows."
It seems that most of the relatively recent revision/movement of the bugs in question has occurred between Centroptilum and Procloeon. I'm not sure if current concepts of these genera are still bouncing back and forth, but as I understand it, both now include adults that may or may not have hindwings. Some species of possible importance to (some) anglers are still (or currently) in Centroptilum. These include C. album, C. almance, and perhaps others
That is unless one has the habit of packing a microsope in their vest and towing an entomological library around.
