There is absolutely no movement in a buzzer coated in superglue or HaN. Ir deceives solely on its appearance and by being where a buzzer ought to be.Ah, but movement of and in the fly pattern signifies life.
I hardly doubt the OP is skating "pellet flies" across the surface. I've never seen a pellet move.
Imitating pellets... and there I thought I had heard it all. I'd rather take up another hobby.
old hooker, I don't use breathers on my buzzer patterns, and if I did they would be of white Antron which is man-made. Many of my buzzer patterns use Spanflex for the body, tying thread for the thorax and holographic tinsel for the cheeks. Nothing "natural" there.
Having said that my most successful go-to buzzer for Farmoor is an updated Cove nymph using cock pheasant for the body, and a seal fur mix for the thorax behind a black, copper or silver tungsten bead. I'd as soon leave my rods behind as go fishing without that one.
