Fulling Mill White Bead Pheasant Tail - Barbless Jig

A signal you cannot see

Trout see further into the ultraviolet than we do, and they appear to use that extra range to sort real food from drifting debris. Put a UV torch on this fly in daylight and the bead lights up. It is not glow in the dark, it is a signal in a part of the spectrum a fish reads and you cannot, and it makes the fly read as food rather than as a floating stick. Best used to pull fish in big open water where they have to find it.
