Hook 3XL streamer hook, #8 (tied here as a micro streamer)
Thread Black 70 denier (140 would make the head faster)
Materials
Lead-free wire, 0.020 n/a (Enough wraps to cover the front half of the shank)
Crystal Flash Orange (any color works) (Three strands of micro flash, folded so it sits above and below the marabou)
Marabou (tail) Black marabou (One good tuft, about a hook length)
Dry fly hackle (palmered) Grizzly hackle (One feather, four or five turns)
Chenille, medium (back/wingcase) Black (peacock herl also works) (One length, folded over the top)
Wool yarn (belly/body) Orange (floss or dubbing also work) (One strand)
How to tie it
Wrap 0.020 lead-free wire over roughly the front half of the shank, start black thread behind it, dam it front and back, then take the thread to the bend.
Tie in three strands of small orange Crystal Flash at the bend (one or two strands if you have standard-diameter flash).
Tie in a good tuft of black marabou about a hook length long over the flash, using the marabou butts and some loose wraps to fill the step behind the weight, then trim the butts (taking care not to cut the flash).
Fold the flash back over the top of the marabou and lock it down so the flash sits both above and below the tail, then trim it just short of the marabou tips.
Tie in the three body components in the reverse order of use. First, strip a short section of a grizzly dry fly hackle and tie it in at the very back, concave side facing forward.
Next tie in medium black chenille (strip the fibers off the tie-in end so only the core is bound down) at the back, this becomes the folded-over back.
Last, tie in the orange wool yarn at the front and bind it down along the top of the shank to avoid a lump at the tail, then wrap it forward to about two eye-lengths behind the eye and tie it off.
Pull the black chenille forward over the top of the orange body, keeping it symmetrical, and secure it with a few wraps behind the eye. Trim the excess.
Palmer the grizzly hackle forward over the body in four wraps, with the fifth as the front wrap, and tie it off. Tying the feather in with the concave side forward makes the barbs cock slightly forward and push a little more water.
Pull the hackle back, build a small thread head, whip finish and add a drop of head cement.
