Midge Flash is a micro version of the popular fly tying material Krystal Flash. This small-diameter twisted mylar flash is a popular choice when tying midge dry flies and nymph patterns when you need that added sparkle. Many saltwater fly tiers use Midge Flash for bonefish flies and small saltwater streamers. Midge Flash is a versatile fly tying material and is available in a ton of fish-attracting colors. Try a few colors out and see how much of a difference it can make. We can't recommend this stuff enough!
