An emerger pattern tied with stripped peacock quill as the body, a small thorax made out of peacock dubbing, and a Cul-De-Canard wing to keep the fly in the surface film of the water. This pattern is tied in the style of Davie McPhail's excellent video which can be found here.
Place the hook in the vise and secure the thread behind the eye. Cover the hook shank with thread to about a quarter of the way down the hook bend.
Catch in a stripped peacock quill and return the thread to opposite the hook point or slightly past.
Wrap the quill along the body to create a segmented look, secure opposite the hook point and cover the tag end removing any excess.
Cover the quill with lacquer or UV resin to improve durability and give the body some additional sheen.
Return the thread opposite the hook point and catch in a short length of floss. Pulling the floss towards the rear secure it with wraps and position it on the bottom of the shank.

Trim the floss to create two short tags.
Align the tips and measure two cul-de-canard (CDC) feathers to be the length of the hook. Catch in on top of the shank and secure the feathers while creating a base for the thorax. Leave enough room to form a small head behind the eye.
Form a dubbing rope and then create an even small cigar shaped thorax ending at the front of the thorax.
Pull the CDC wing over the thorax to form a wing case and secure with thread.
Take a few wraps in front of the CDC wing to stand it up, and then finish securing with a whip finish behind the wing.
Snip the thread and apply head cement to finish the fly.
