Head / hot spot Fluorescent orange (or red) thread, or a coat of fl. orange UV resin (-)
How to tie it
Start black thread behind the eye and run to the bend. Tie in 6-8 brown cock hackle fibers for a short tail about half a shank-length long.
Tie in a strand of red Ultra Wire at the bend, then 2-3 strands of bronze peacock herl by their tips.
Wrap the peacock herl forward to about the 80% point to form a slim body and tie off; leave room for the head.
Rib the body with 4-5 evenly spaced open turns of the red wire (this both segments and reinforces), then helicopter off the excess.
Tie in a small bunch of brown cock hackle fibers underneath as a swept-back beard/throat, reaching to about the hook point.
Switch to fluorescent orange thread and build a distinct bright band/head in the front 20%, whip finish. Optionally coat the head with fl. orange UV resin for durability. This hot head is the pattern's trigger.
