Krystal Flash and Flashabou
Hareline Krystal flash is used in numerous fly patterns, and the glow-in-the-dark saltwater version can be added to almost any fly. The material is slightly stiffer than the regular Krystal flash, but it can be used for streamers, nymphs and dry flies. The Hedron company also makes a glow-in-the-dark version of flashabou. The material is not as stiff as the Krystal flash, but it serves many of the same purposes. The glow in the dark flashabou comes in white, pink, yellow, blue, orange and green.
Polyyarn and Chenille
Polyyarn comes on a spool and can be cut to any length. The strands of material can be used for tails and wings, or it can be wrapped around the hook shank for a glow-in-the-dark body. Several versions of glow-in-the-dark chenille are also available and can be used for the body of most flies.
The heads of most flies use thread, and glow-in-the-dark thread can complement other glowing materials. Glowing tying thread comes in 3/0 strength, but the Gig Harbor Fly Shop claims that it is not as strong as standard 3/0.
Glow-in-the-dark paint has a variety of fly-tying applications. Glow paints can be used to paint on eyes, color rubber legs and to paint stiff fly bodies. Use a nontoxic version that can be covered with a clear coat of epoxy or clear nail polish.
