I just saw this fly over at Reno Trout Envy, it is the Lightning Bug - nothing too fancy, but very flashy and easy to tie (not to mention the photo is excellent as well).
I have tied a few of these and they do kind of look like the rainbow warrior, and they do work - especially in off color water. You can tie these even smaller - all the way down to size 24 as my buddy Darren does - with a sort of purple tinsel that is only a mm wide. This tinsel needs to be glued down to hold it in place and because it can be brittle when trying to pry it out of a fishes mouth with forceps.
These flash/tinsel flies are easy to tie, can be tied all the way up to a size 10 or so and the colors can be any color you can dream of (just look at some of the colors Brian used in his fly box.
This is a great, easy to tie fly that produces. Thanks Brian for another great fly!!
