Blue Wing Olive by Big Y Fly Co.
The Blue Wing Olive is a must-have for matching one of the most consistent and important mayfly hatches across trout fisheries. When conditions turn overcast, cool, or damp, BWO hatches can blanket the water—and this pattern is built to match those small, subtle bugs that trout key in on.

FAQ
What makes the Blue Wing Olive different from other mayfly imitations?
It has a slim, natural profile that closely mimics the actual Blue Wing Olive dun, with a low-riding action that sits in the film where trout typically target during overcast conditions.
Is this fly suitable for use in clear, sunny weather?
No, it performs best in overcast, cool, or damp conditions when Blue Wing Olive hatches are active. In clear, sunny weather, it may not be as effective.
Can this fly be used in fast-moving streams?
It is primarily designed for slow-moving or technical waters where trout are selective. Use with caution in fast-moving streams.
Victor Alsop –
Used this fly during a drizzly morning and caught two trout in under 30 minutes. The presentation was natural and it stayed in the film perfectly. Great match for overcast conditions.
Wendy Henderson –
Felt like the real thing when fishing in cool, misty weather. Trout were actively feeding and this fly triggered a good number of strikes. A reliable choice for BWO hatches.
Stephen Carr –
Perfect for slow water and pressured fishing. The low profile and natural movement made it hard to miss. I’ve used it in multiple trout streams and it consistently works.
Phil Kerr –
It’s not a one-size-fits-all, but when the weather is overcast, it’s a solid choice. The fly holds up well and doesn’t float too high in the water.
