Squirrel dubbing (body) Natural gray-brown squirrel dubbing (A 3 inch noodle)
Partridge fibers (wing case) Natural gray/brown hungarian partridge (2 clumps of about 10 long side fibers)
Squirrel dubbing blended with acrylic (thorax) Dark gray, darker than the body (A short noodle)
Hungarian partridge hackle Natural gray partridge fibers (1 good feather)
Tying wax Clear head cement (As needed for the squirrel)
How to tie it
Mount a size 12 1X-long nymph hook and lay a gray thread base down to the start of the bend.
Take about ten fibers from a small partridge feather and tie them in at the bend as a short wispy tail with a pinch wrap. Bury the butts and run the thread up about two thirds of the shank.
Tie in small silver wire for the rib and bind it back to the tail.
Wax the thread and dub a loose, buggy noodle of straight squirrel, guard hairs and underfur mixed, about three inches long. Wrap it forward over the back half to two thirds of the shank. Buggy is what you want here.
Wrap the silver rib forward in close tight turns to lock the loose dubbing in and shape the body. Tie it off with a couple of wraps, then take a couple of wraps forward over the wire so you can lift it and helicopter it off without unravelling.
Take the thread back and tie in about ten long partridge side fibers as the wing case, then a second clump of the same thickness a little further back so the case has body. Bury or trim the butts.
Wax again and dub a shorter, tighter noodle of the darker squirrel/acrylic blend for the thorax. It should read distinctly darker than the body.
Tie in a good Hungarian partridge feather by the tips, with a small V notched out and the concave side toward the hook, taking the wraps back a little so you do not crowd the eye. Fold it back on itself and secure. Snip the tip.
Take one full turn of partridge with hackle pliers, bring it back to the near side and tie it off. Snip the excess and push the fibers down and to the sides as legs.
Fold the partridge wing case forward over the thorax, using it to help hold the legs down and back. Tie it down with two or three wraps, back the thread off a turn if it slips, then lift and trim the excess short.
Build a good-sized nymph head with a ramp back to the eye, whip finish, then trim any legs off the bottom so you are left with four or five per side. Finish with a drop of head cement for a hard shiny head.
