Attach 8/0 brown or gray thread to the shank of a dry-fly hook, size 10–14, about a quarter of the way down its shaft from the eye.  Strip a clump of fibers from a wood duck flank feather. Secure this wing, tips forward, to the top of the shank.  Trim the butt and wrap the thread back to a point just above the barb.  Strip some stiff fibers from a dark ginger spade hackle and secure to the top of the shank so that their tips protrude about three-quarters of a shank-length past the bend.  Attach a length of heavy yellow thread at the tie-in point for this tail.  Twist some tan or gray beaver fur onto your thread, then evenly wrap it forward, stopping just behind the wing.  Bring the yellow thread forward over this dubbing using widely spaced wraps and secure.  Select two ginger-colored hackle feathers and attach them, butts first and with the concave sides up, just behind the wing.  Wrap thread forward, stopping just in front of the wing.  Wrap hackles forward, secure, and clip the tips.  Finish the fly with two or three half hitches just behind the eye, clip the thread, and apply a tiny drop of head cement.
