Biot Sparkle Dun - Baetis Olive

The Biot Sparkle Dun in Baetis Olive is a versatile dry fly designed to match the natural olive mayflies found in Montana's streams. Featuring a segmented biot body that creates realistic movement in the water, this pattern combines durability with a subtle sparkle that catches light and fish attention alike. The olive coloring mimics the natural hue of baetis duns during their emergence, making it an effective choice during spring and fall hatches. Tied on a quality hook with a traditional parachute or upright wing style, this fly floats well and remains visible to both angler and trout. A reliable pattern for selective feeders targeting small to medium mayfly imitations.
