Just concentrate on the white smurge on the leftmost of the head shot. What the heck causes that? Nothing in the other shot to cause it.
I don't get it.

I can't tell what you're talking about. Which image, what coordinates?

I still have this fly set up, and it occurred to me just now (duh...) to do a direct visual inspection -- naked eye and with 10X loupe. Sure enough, a lot of those bristles act like tiny cylindrical mirrors, becoming very bright when the light, the bristle, and the eye are in just the right positions. Move the eye, and the bright bristles go dark while some others get bright instead. On direct visual, a small fraction of the bright reflections are intensely colored.
