I mentioned having seen this Caddis pattern in the Beartooth Fly Shop along the Madison near Cameron, Montana in another thread
Can't speak to its effectiveness as the little pattern I was fishing worked so well, I didn't even try it.
But, I thought others might like to see it
I believe his shop calls it the "Delectable Sparkle Caddis". It is my understanding, that if the shop owner came up with the fly design, it carries the moniker "Delectable".
