Grizzly dry fly hackle feather Grizzly hackle (1 feather, supplies tail, body quill and hackle)
UV resin Clear uv resin (One small drop over the quill body (tyer's addition))
How to tie it
Lay a base of black thread from behind the eye to the bend of the hook.
From a single grizzly dry fly hackle, strip 10 or 12 of the longer barbs from toward the fat end and tie them in at the bend as a tail. Go fairly long. This style of dry fly wants it. Snip or bury any curled ends.
Strip a couple of inches of barbs off that same feather to expose bare quill. Tie the quill in a few millimetres forward of the bend with the thinner end toward the rear, then bind it back to the tail.
Leave the thread at about the 75% point, grip the quill with hackle pliers and wrap it forward in touching turns to form the body. Do not obsess over gaps. The resin will fill them. If your quills are brittle, soak them first; pliable ones wrap straight off the feather.
Tie the quill off with two or three very tight wraps, pulling the thread up hard so the quill cannot slip back, then take a few more wraps before snipping the excess. Squash any small nub flat.
Put the smallest drop of UV resin on the quill body, spread it evenly with a bodkin or the bottle's stopper while rotating the fly, then cure it for about 15 seconds. This makes the body durable and gives it a hard shine.
Take what is left of the same feather, now at the thinner end, take one wrap back so you catch it in at the front of the body, and bind the stem down along the shank. Trim the stub.
Wrap five turns of hackle for a generic mayfly, or three sparse turns if you are tying it as a true mosquito. Tie off with three wraps and snip.
Pull the hackle back, make room, whip finish, and check that tippet still passes through the eye.
