Blue Winged Olives are one of our best hatches in our Black Hills Streams, as with many other trout waters throughout the country. There's a myriad of different BWO patterns, but a standard Parachute BWO will often produce just as well as anything else. This is definitely a pattern to always stock in your boxes!
