How to tie it
Slide a 5mm jig bomb bead onto the jig hook small-hole first so the concave side faces rearward and blends into the body, then chuck the hook point-down in the vise (the fly is tied upside down relative to how it fishes).
Start olive 72-denier thread, run a base slightly around the bend and back up to the bead, and set the bead well back from the corner of the shank so there is room to tie the front of the fly.
Lock the bead in place with figure-eight-style wraps in front of and behind it, checking that it sits square on the hook; flip the hook, add a heavy drop of super glue over those wraps, and take more wraps to bed the glue in.
Bring the thread to the midpoint of the shank and form a 3-4 inch dubbing loop; load it with peacock Ice Dub and spin it with a dubbing whirl, then align the fibers into a thin strand.
Bind the loop down rearward to the start of the thread base, then bring the thread forward to the bead.
Wrap the spun dubbing forward in butted turns to the back of the bead, tie it off in the recess behind the bead, and trim the excess; sweep the fibers back lightly rather than picking them out.
Jump the thread in front of the bead and wrap a thread base around the corner up to the hook eye and back to the front of the bead so nothing slides.
Build a second dubbing loop, load it with the long-fibered tan UV Ice Dub plus a pinch of pine squirrel fur, and spin it up.
Wrap this loop in front of the bead up to the eye to form the collar and head, stroking the fibers back with each turn so they sweep over the body.
Tie off, build a small thread head, whip finish and add a drop of glue.
