Curtis Fry put together a nice vid for a foam bodied Callibaetis

Dubbed version, along with a tan-bodied Spundun, worked well for fall drakes in YNP ; foam gives it a bit more lift. Subbed twisted brown Congo Hair for the rib and barred tannish/cream hackle. I know it's mid-July, but it's not too long before they start showing themselves (and I'm probably not going to be doing much fishing 'till then anyway)
Thanks to Bob Quigley for the original idea

Scott
