Best Blue Winged Olive Fly Patterns

Split Flag Quigley BWO

The most noticeable aspect of the Quigley Split Flag is the black post that extends so high above the shank. This paraloop style fly floats low in the water, which the fish notice, while the extended Angel Hair makes it easy to see for the angler.  This is a quintessential guide fly, relatively easy to tie, very easy to see and with enough strike inducing triggers to make it well worth tying.

Swishers Clumpa

The Clumpa style was designed by Doug Swisher, noted fly designer and author. The Clumpa BWO is a low floating fly with a unique profile on the water. Because the hackle is folded during the tying process, it provides a silhouette that is not available on any other mayfly dry. We are all about showing fish something different, especially when fish have been on a hatch for a while. Blue Winged Olives will hatch from mid-September to late November- ample time to get familiar with their shape! The Clumpa shows them something a little different.

BWO Last Chance Cripple

The Last Chance Cripple was invented by the Harrops for use on the Henry’s Fork, and this fly works. Especially on a blanket hatch like the BWO, when the fish will definitely focus on a specific phase of the hatch. The CDC provides excellent attraction, while the stripped peacock herl body is thin and life-like. We carry the Last Chance Cripple in many different mayflies, because it is so effective,

Bullet Olive Perdigon

The Perdigon nymph has become Missoula’s hottest fly style, and has been working all across Montana. This awesome BWO nymph sinks rapidly and stays in the zone. The jig hook design almost eliminates snags on the bottom, which allows you to lengthen the dropper to stay closer to the bottom.

Blue Wing Olive Comparadun

Our Missoula fly fishing guides wouldn’t head anywhere in Montana to fish the Blue Winged Olive hatch without taking a few Comparaduns with them. This low floating fly produces in the colder waters in the spring, providing a realistic silhouette. The Comparadun can double as a spinner if you trim the tops of the wing off.
