Although the fly’s buggy enough, as is, I added some partridge up front. Not sure if the hatch is still happening in YNP; if you miss it in the spring it happens again in September. Here’s the video if you’re interested.
hook - WFC Model 3 #14
thread - MFC 8/0 light olive
body - Zelon dubbing white miller
wing/waking post - Congo Hair white
hackle - barred cream (oversized by 1)
collar - partridge
