Hawn that one's been around a long time, night fishers after big largemouths in the south cast all black jitterbugs, they worked but I think alot had to do with the sound made by the bait bopping back and forth from the metal plate in front.
I like how the satin fibers look, and in the pic when wet but all the UV stuff - this for me is making decent jigs and catching some great eating fish - I do enough tech stuff at work!!!!!!!!
It's because of the way light behaves underwater at night. All the light comes from the surface. Fish that hunt primarily by sight and feed upward like crappie are looking for the silhouette of prey passing overhead against the backdrop of the illuminated surface. They can also sense targets through their lateral lines, but they rely on their eyes for the final approach and strike.
When I'm fishing at night, I usually switch to a jig with a dark body and bigger profile. My favorite is the black cactus chenille since it's dark, reflective and gives the jig a nice poofy body.
As far as UV goes, UV light is not visible to humans, period. Fluorescence and UV are not the same thing. I have heard a lot of manufacturers are claiming UV when their lures or materials just fluoresce.
There's a company out here that makes yarn for tying yarn balls for steelhead, and they've slapped a UV sticker on every single color, including black. Think about that for a second. UV reflecting from the color that is by definition the complete absence of reflected light.
So while some species of fish can see UV, there is no way to check whether the materials or lures you are paying extra actually reflect UV light without a camera equipped with special lenses. It's nice to have, but I would not pay extra for stuff that claimed UV.
