They are making glow in the dark flashabou in a bunch of colors now. I have in this fly, Chartreuese, Yellow and Orange. They are mixed in with bucktal of their respective colors. The fly looks pretty normal in regular light.
If you turn the light off though.
I think this is an improvement over my previous glow in the dark clousers. If I can find a blue that glows blue, I can stop hunting for it.
I also used a glow in the dark thread. I'm not all that happy with it for Clousers. It breaks easily and outglows the rest of the stuff. Rudolf Clousers.
