Heres a nice little addition to your fly patterns. This fly is “money” on the Farmington and a solid tie for the box of any fly angler. This fly is designed to be very heavy and drift along the bottom, “rolling” in between rocks and boulders where trout lie waiting for food to pass by. That being said you should fish this fly in swift rocky runs and the current seams directly behind them where this insect flourishes. You can fish this with a Czech, Polish, Euro, or any other style of fly fishing nymphs, the key being the weight that keeps this bugger down in the strike zone.
A solid glowing, twilight pattern for those out there searching for those large trout that many times will only come to the surface to sip insects in the cover of darkness. Enjoy!
