I fish that pattern. Where did he go ? I used to run into him back in the 80's on DF and the Ford. I had a video he made called fishing the midge that was great back in the early 80's and that is where I saw this pattern and my all time favorite the Cone head. That guy was friggin God !!!!!
I posted this as I've seen questions about it occasionally and there's nothing that came up on searches. The butt is Ostrich herl. Fish it anywhere chironomids or midges are emerging and the fish are taking from the surface.
Raccoon: Like a Lady McConnell with no hackle. Pg 25 of Rowley's 'Fly Patterns for Stillwaters'. Pattern by Paul Lasha.
Hook: Dry 12-18
Thread: to match body.
Tail: teal flank feathers or grizzly hackle. (Lady McConnell also has a few strands of white z-lon, but not in the raccoon pattern.)
Butt: White ostrich herl, sparkle yarn, or antron.
Shell back: Elk or dark deer.
Body: SuperFine or rabbit dubbing.
Note: He doesn't give a color. I've used peacock for the body, but I assume black, dark olive, etc. to match the emerging chirono.
I nailed my biggest rainbow on this fly in public water. My recipe used black floss for the body and a few turns of the grizzley hackle instead of the ostrich herl. It's dumbfounding how effective this pattern can be!
