Here is a video on how to tie the Royal Gorgeous Caddis. It's a simple fly to tie, the hardest part is making the dubbing. I use a mixture of 3 dubbings, but you can mix what you like and probably do just fine. Take a look.

This little caddis pattern works great anywhere there are caddis larva and pupa drifting around. It is based off of the Cimarron Special, a pattern from Greg Faught, one of my favorite patterns of all time. This is a very simple pattern to tie and the key is the buggy rubber leg dubbing.
