Brian Chan's Ruby Eyed Leech

With that red in their eyes, and a fierce bite to boot, the Red Eye Leeches swim deep and move with realism. Make sure you have a few in your streamer box.

They are an extremely effective fly pattern for everything from steelhead to big browns. The Ruby Eye Leech has it all -- multi-coloration in the body, a tiny conehead for an undulating motion in the water, and a small red glass bead that seems to be some kind of magical fish call to stillwater trout. Get 'em while they're hot.
