Hook Dry fly hook; the video uses a 3X-long dry/terrestrial hook, #12-16
Thread Red 140 denier
Materials
Peacock herl Natural peacock herl (2-3 strands (butt and thorax))
Calf body hair (white deer body hair substitutes) White calf body hair (Medium tuft for the wing)
Dry fly hackle Brown hackle (1 feather)
Head cement Clear head cement (1 small drop)
How to tie it
Pinch the barb and start red 140 denier thread just behind the eye. Wrap back to the 30% point (just past the start of the bend). The red thread is the body, so the return trip will give you a second layer.
There is no tail. With the thread hanging at the 30% point, tie in two or three strands of peacock herl and bind them back a few wraps. Wrap the herl forward into a fat butt, five or six turns, then tie off and break the excess away. Peacock herl from the small end is brittle. If a strand parts, just catch it back in and carry on.
Spin the thread counterclockwise to flatten it and wrap forward in touching turns to about the 80% point, building a smooth red thread body over the whole shank.
Stack a medium tuft of white calf body hair (or white deer body hair). Measure it so the tips reach a little past the bend and tie it in at the 75% point as a single upright/trude-style wing, taking three or four tight wraps with corded thread. Let it flare in front; that will be trimmed.
Snip the front butts off in several small cuts and wrap over the stubs to flatten and smooth the wing base. Check the wing from the front and snip away any fibers that have splayed out to the sides. You want the red body still visible from below.
Tie in a brown dry fly hackle by the stem at the back of the thorax (right at the wing base), leaving the stem a little long to help smooth the underbody, then trim the butt.
Tie in the remaining peacock herl at the front, wind the thread back over it to the wing base, then bring the thread forward. Wrap the herl forward in five or six turns to build a thick thorax and tie it off behind the eye.
Palmer the brown hackle forward through the thorax in four or five open turns so peacock still shows between them. Tie off, pull the fibers back to open room at the eye, and trim the tip.
Build a small dry-fly head, whip finish, and add the smallest drop of head cement. Clear any stray fibers blocking the eye.
