ok thank you normand. i knew that biots were the short stiff leading edge primary feather fibers and what not. and i also knew that my green ffeather had biots on the left edge. and the fact that the black feather had none of these short stiff fibers is what got me. now i kno that the bag the black feather was in was improperly labeled.
The green feather in your picture.

some people use the long biots on the right side of the feather as wing cases. They work quite well for stone fly wing case humps.
