Tail Blue dun hackle fibers (long, one and a half shank lengths)
Body Stripped brown hackle quill (lacquered)
Hackle Oversize blue dun (5-6 turns, no wings)
How to tie it
Mount hook and start thread; this is a wingless variant, so hackle quality is everything.
Tie in a long blue dun tail, one and a half shank lengths, for support.
Tie in a stripped, lacquered brown hackle quill at the bend and wrap a segmented body to the 75% mark.
Wind an oversize blue dun hackle (one to two sizes larger than the hook) in 5-6 turns. The big hackle floats the fly high in broken water and imitates the blur of wings.
