Invicta Flies - Porcupine Dun
The thicker bristles found on a porcupine can be used as a body material. The coloration and shape of the quill produces a distinct segmented body. The natural color is typically in shades of tan with a slight dun tint, but can be dyed to match different mayflies as well. The finer, longer hairs of the porcupine can also be used for dry fly bodies and is becoming popular as a quill substitute.

Notes: To use the shorter, stiffer bristles from the porcupine, soak in water a few minutes, then run the bristle between your thumbnail and fingerpad to flatten it. Tie it in at the bend by its tip, then wind it forward.
