About

Blue Wing Olive (BWO) Flies Quick Picks Best All-Around BWO Dry Fly: Blue Winged Olive Dry Fly - A straightforward, buggy imitation that covers the widest range of BWO species and water types. Keep this in sizes 16-20 for any tailwater or freestone stream from late winter through fall. Best for Picky Tailwater Trout: Juju Baetis Tungsten Bead Fly - Built for pressured, gin-clear water where fish have seen every generic nymph. Its slim SuperHair body and realistic profile get eats when standard bead-heads get ignored.

The heavy bead and slim profile drop it into the strike zone quickly.

It covers go-to imitations for shoulder-season hatches so you are not caught without the right pattern. Best High-Visibility Parachute: Parachute Blue Winged Olive BWO Dry Fly - Suited to anglers who struggle tracking small dries on broken or glary water. The post rides low like the naturals but stays easy to pick out at distance. How to Choose Blue Wing Olive (BWO) Flies Dry Fly or Nymph Dry flies: Fish these once you spot rising fish or steady surface activity, typically during the hatch window on overcast, drizzly afternoons when BWOs pop in numbers. Nymphs: BWO nymphs work all day, every day, since trout key on Baetis nymphs drifting near the bottom far more often than they eat the adult on top. Start subsurface if nothing is rising. Size Selection Sizes 18-22: Match these to the smaller late-season and tailwater BWO broods, especially on heavily fished rivers where trout inspect flies closely. Sizes 16-18: Cover the more common early-season and freestone hatches, giving you a fly that is easier to see and tie on without sacrificing realism. Pattern Style Parachute style: Choose this for
