The giant Salmonflies of the Western mountains are legendary for their proclivity to elicit consistent dry-fly action and ferocious strikes.
I am seeing a good amount of what I believe to be psuedocloeons in the stream...about a size 22. What color would you recommend tying the abdomen and thorax of the emerger and/or nymph?
Iswaeon anoka was first brought to the attention of the angling community (as Pseudocloeon anoka) by famous angling author and columnist Joe Brooks. Back in the late 60's he wrote an article for Outdoor Life magazine extolling the work of Doug Swisher and Carl Richards in their forthcoming and groundbreaking book, Selective Trout. This species was featured as the model for their now famous version of the "No-Hackle" dry fly and imitative parachute patterns, sparking a revolution in fly design for hyper-selective trout. The rest as they say, is history...
Other option is to wrap rooster hackle and trim flat the fibers below the shank...I was up late one night drinking beers with Eric in Coburn PA after a wonderful afternoon on Penn's Creek, and he was tying and we laughingly argued about this short-cut...I saw him do it. :) Truth be known, and you can't tell this to Eric, but the same character mentioned above suggested the same thing to me, for this hatch, back in the early 90's...)
