As I have previously noted, I first fished the Roxy Rainbow on East Lake (Oregon). A Bend, Oregon guide named Russ Seaton provided the recommendation and the fly. It worked well that day, not just because of the fly but also because of his instructions on how to best present the fly in the pre-emergent/emergent phases. A similar fly is the Lightning Bug, a flashy nymph pattern depicting the nymph aglow with trapped gases. The Roxy Rainbow was designed by Tim Paxton according to Sunriver Flyshop owner Bob Gaviglio. Once again, the flash is important and the presentation. You will greatly increase your pleasure in fishing if you think about presentation and not just idly kick about trolling a fly and picking up the occassional fish. How to tie it is pretty evident from the photos. If a pattern seems baffling then write to me for instructions.

Thank you, Gary for enquiring:
Thread: 8/0 Black
Hook: Sizes 12-16 straight shank hook. Materials for this fly lend themselves to a smaller fly, so experiment.
Tail: Mallard, Teal, Gadwall, Partridge; no longer than shank or shorter
Body: Rainbow Krystal Flash; 3-4 strands or less, depending upon size of body, wrapped 2/3’s up shank.
Ribbing: Any fine wire. I have experimented with copper, gold and silver.
Thorax: 1-3 strands of peacock or small amount of Peacock Ice Dub.
Hackle: Partride or any of the above feathers used for tail. Apply in similar fashion as Cal’s Bird Nymph, with fibers applied not wrapped but pinched around the thorax area being careful the fibers do not overextend back too far.
Finish off head. I have also seen this fly with a greenish or bluish bead for the thorax. This is a pretty simple pattern to tie. Good luck and enjoy this fly on the lake and in rivers as well.

Yes! I would like the materials list for the Roxy Rainbow fly. I just want to make sure that I tie it correctly.
Thank You.
