Stack a small clump of elk hair and tie it in as a tail about a half shank long at the bend.
Dub a tapered, slightly rough abdomen forward to the 65% mark. Leave it bare of palmered body hackle. That omission is what makes it 'naked' and lets it sit lower and buggier.
Stack and tie in an elk-hair downwing at 65%, tips reaching the end of the tail, and trim the butts to a short stub.
Dub a small thorax ball just in front of the wing.
Tie in a grizzly hackle and wind 4-5 turns through the thorax only, then tie off.
Whip finish, add a drop of cement, and trim any stray fibers.
