Top 10 Blue-Winged Olive Montana Fly Fishing Dry Flies

These small, olive-colored Mayflies emerge underwater on cloudy days and spend several minutes on the water’s surface as an adult or “Dun”. Trout actively feed on the emerger and dun Blue-Winged Olive stages for a few hours when Bozeman fly-fishing conditions are cool and cloudy during the Fall months. Rising Trout can be found along foam-lines, bank-side seams, and slow tail-outs on the Montana rivers near Bozeman when Blue-Winged Olives are hatching. Having a good selection of Blue-Winged Olive dry fly patterns that imitate the emerging and dun stages of these Mayflies is essential for success when fly-fishing to rising Trout near Bozeman.

Our Bozeman fly-fishing guides spend a great deal of time on the water during the Fall – both on guided Montana fly-fishing trips and on their day's off – with dry flies throughout Southwest Montana. Here are our fly-fishing guide’s top 10 favorite Blue-Winged Olive dry fly patterns for our Bozeman fly-fishing outings during the Fall.

Experience Blue-Winged Olive Dry Fly Fishing in Bozeman, Montana

After months of minimal hatches on the Montana rivers near Bozeman, the arrival of Blue-Winged Olive hatches are among the key signals that Fall has arrived. Although many anglers associate stripping large streamers with Montana fly-fishing this time of the year, the slow rise of a trout during a BWO hatch on the Madison or Yellowstone River will stop the experienced fly angler in their tracks. Be sure to have a varied selection of both Dun and Emerger BWO fly patterns on hand during your next Bozeman fly-fishing outing this Fall.
