How To Tie: Night Leach

Night Leach. This pattern can be used in any waters that contain big trout.

This fly, created by my dad, Steve Probasco, has become my “go to” leach pattern – especially in the evening hours. Not only is this fly good for trout, but when tied in a variety of colors; brown, blue, purple, red, etc., it is a great smallmouth bass fly too.

As Steve writes in his book “Probasco’s Favorite Northwest Flies“:

When the body material Estaz hit the market, I started tying leech patterns using this innovative material for the body of my favorite leach patterns. Fishing during darkness, a few of my buddies finned side-by-side in their boats. We were all using leech patterns, but those of us who were using leeches tied with Estaz for the body out-fished the leaches tied with more conventional body materials. Coincidence? I don’t think so. Numerous outings under the same circumstances proved to us that, at least at night, leeches tied with Estaz for the body outproduced all others…hands down!

For trout, this fly should be fished very slowly along the bottom, in a “leech like” fashion.
