Blue Wing Olive
Exploring the Timeless Allure of the Blue Wing Olive (BWO): A Fly Fishing Classic
In the intricate dance between angler and fish, few flies stand out as much as the Blue Wing Olive (BWO), also known as Baetis. This historical pattern has fooled trout for longer than many of us have been alive. Recognized for its olive body and dun (or gray) wings, the BWO is an imitation of the mayfly Baetis, a small insect that, despite its diminutive size, is commonly recommended in hooks ranging from 18 to 22. This insect consistently entices notably large trout.
The BWO shines in its versatility, often considered "the winter bug." Its hatching cycle can be triggered even in the cold months, offering dry-fly purists an option during colder seasons. It's not just an essential food item in the trout diet but also a refreshing break for anglers tired of winter nymphing.
Tying and Fishing Techniques
When tying these flies, there are significant considerations. Given their small size, working with these hooks can be frustrating at first, but with practice and perhaps a pair of reading glasses, you'll soon be casting small mayflies with skill. Although the name suggests a very rigid formula, these flies are open to interpretation. Many tiers add details like flashes or different color bodies to accommodate changing bug patterns throughout the seasons.
History and Varieties of BWO
Blue Winged Olives are first mentioned in Frederick Halford's Dry Fly Entomology in 1897. Their history includes various names such as Olive Duns, Blue Duns, Iron-blue Duns, and Olive Quills. In the general description, BWOs are divided into two main types: light-gray wings with an olive body and medium to olive-brown wings. These insects are fundamental in the trout diet, and tiers have created numerous patterns to mimic their various stages.
Effective Fishing with BWO
Fly fishing imitating Blue Wing Olives requires patience and observation. Nymph imitations are effective when these insects move from the gravel substrate. Emergers, in both nymph and parachute forms, mimic the ascent of BWOs to the surface. Dry flies reproduce the mayflies drying their wings on the surface before flight. Spinners capture the moment after mating and egg-laying.
Gear and Techniques for BWO
Choosing the right tippet and leader is crucial to effectively imitate BWOs. Typically, fishing with 4x, 5x, or even 6x tippets is suggested due to the small size of the flies. A 9-foot leader in 4x is a solid choice, with the addition of 18 to 24 inches of fluorocarbon tippet in 4x, 5x, and/or 6x. The use of fluorocarbon aids in presentation, as it does not create ripples on the water's surface, avoiding alerting cautious trout.
Conclusion: An Iconic Fly for All Seasons
The Blue Wing Olive is a fly that goes beyond being a mere fishing tool. It's a connection to the rich history of fly fishing and a versatile tool that can be effective in any season. Its ability to lure selective trout to the surface and its adaptability make it an indispensable companion for any fly fisherman. As you cast your BWO imitation, you're participating in a tradition that spans generations, an eternal dance between angler and fish.
