A Google search tells me is a fly that the Deschutes Angler in Maupin has cooked up. If you really want that fly, I would not worry about tying it, but just drop a little coin at the DA shop, then post its pattern here.
I see that some yarn is hard to get in order to make it, so the only choice is to buy it.
Designed by Amy Randall-Hazel, the Rx to the best of my knowledge is;
HOOK - Salmon/Steelhead, up-turned loop eye
TAG - Chartreuse Floss
TAIL - Hot Orange Golden Pheasant Tippets
BODY - Plum-colored Yarn
RIB - Silver Oval Tinsel
Collar/Hackle - Purple-dyed Guinea
WING - Polar Bear, accented with a few strands of Silver Holographic Flashabou
HEAD - Purple thread
I tie a slightly 'dressier' version (Faux Lum Plum) of the L.P. with combination Orange G.P. Crest and Tippet Tail, an Ostrich Herl Butt, and "Plum" Iridescent Dubbing in the body. I also have the LP tied as a Tube Fly
If you'd like a macro (.jpg) of either dressing, just shoot me an e-mail ([email protected]) and I'll try to accomodate.
