Goose wing quill fibers (or turkey, pheasant tail) Natural gray pheasant rump (3-4 fibers for the body)
Wide hen or rooster body feathers Dun gray (black or brown also work) (2 feathers, paired, for the wing)
Flexible cement Clear head cement (A thin coat to bond and shape the wing)
Dry fly hackle Dun, or matched to the body/wing (One feather, one size OVER the hook size, 4 turns)
How to tie it
Prepare the wing first. Stack two wide dun body feathers on top of each other, even the tips, cut the stems off, and strip the lower fibers from both feathers together, using the hook itself as a ruler, until the remaining feather section is as long as the entire hook from the back of the bend to the front of the eye.
Coat the paired feathers with a flexible cement, and as it begins to set, gently draw them into a teardrop shape. Set the wing aside to dry while you tie the rest of the fly.
Attach 6/0 thread and wrap a base back along the shank.
Take three or four fibers off a gray goose quill, tie them in by the tips at the rear, and wrap them forward together to make a finely segmented body. Tie off and trim the excess.
Set the dried wing flat on top of the shank with the point just behind the eye and take a gentle wrap, then wrap BACK toward the body over it. Wrapping back cups the feather over the hook and creates the caddis tent shape.
Split the two feather stems left projecting forward and set one to each side as antennae; you can shorten them later.
Select a dry fly hackle one size larger than normal, bent around the hook it should reach about twice the shank-to-point distance, trim out the webby base and tie it in on the near side, concave (light) side forward.
Take four turns of hackle in the short space available, tie off and trim.
Whip finish the head.
Trim the hackle flat across the top, then invert the fly in forceps and trim the bottom barbs off level with the hook point, laying the scissors right on the shank and taking care not to cut the antennae, so the fly sits flat and low.
