Let's get one thing clear; this is not your grandmother's or grandfather's basic Zebra Midge. No offense to grandma or grandpa, but it's time our beloved Zebra midge received a head-to-toe makeover. That's where RIO's TZM TB comes in. Tied on a scud hook with a matte black tungsten bead contrasts a shinny body layered with a protective coating—did you know real midges have shiny, sometimes mirror-like exteriors? The coating also acts as a protective barrier to trout teeth. Still the best fish-catching midge pupae/larvae out there, but an entirely new Zebra Midge.
