This is our "Korn's Spent Wing Caddis" a great fly and one of my favorites.  I've been tying hundreds of them in tan and olive green.  We fish it as a trailing fly tied about 12-18 inches behind a dry fly, like an X-Caddis or a hopper.  But while I was tying all those flies I got thinking about last fishing season and how well we did catching fish on pink bodied hoppers.  So the next thing I know I'm tying this variation. 
Why not pink?  Pictured is my prototype with pink body and head, I've named it the "Pink Cadillac Caddis".  Think it will catch fish?  I do, but then again, I might just be a little "spent" from spending too many hours at the tying bench!
I hope everyone had a great Christmas and is looking forward to the new year!
