The white fly has a clear bead head, and the material that is the tail is tied around a pipe cleaner body. I'd call it hair, not feather.
The black one too, but has gold bead head.
I actually have two versions of the green one, both have a fluffier feather tail AND a more hair-like one wrapping the body pipe cleaner. One has a gold round bead head, and the variant has a more cone-shaped gold head plus some iridescent strips in the body.
