Wing White generous calf (A generous stacked clump of calf tail)
Tail Natural moose hairs (About five stacked moose body hairs)
Body Dirty yellow (Superfine dubbing (PMD and sulphur mixed))
Hackle Brown and grizzly hackle (One dry fly feather of each)
How to tie it
Start black thread on the front third of the shank of a standard #12 or #14 dry fly hook.
Stack a generous clump of white calf tail and tie it in at about the 65% point as an upright wing, taking several tight wraps going back; lift the butts to a 30 degree angle, lay your scissors parallel to the shank and trim them off close, then smooth the underbody with loose wraps to give it a taper.
Take the thread to the bend and tie in about five stacked moose body hairs for the tail, at least a body length long; add a wrap up under the tail so it can't spin and a couple of medium wraps behind it to control the flare.
Go back to the wing and post it like a parachute post: several wraps at the base, then one or two wraps around the hair itself so it stands up with a good flare.
Take the thread to the bend, wax it, and dub a thin dirty yellow body up to the base of the post. The underbody is already fairly thick, so keep the dubbing sparse.
Tie one brown and one grizzly dry fly hackle in at the post, one wrap behind and a couple on top, then lock them in up front and snip the excess.
Wrap the first hackle two or three turns behind the wing and two or three in front, tie it off with two wraps and snip the excess before wrapping the second.
Wrap the second hackle the same way, zigzagging through the first; tie off up front.
Pull all the hackle back, build a small head, whip finish, then trim the excess feather and clean up stray fibers; add head cement.
