Rio BWO Dry Fly Assortment

The Rio BWO Dry Fly Assortment is a curated collection of patterns designed to match the Blue Winged Olive hatch found on trout waters everywhere. This kit gathers the most reliable imitations of these small mayflies into one convenient package for anglers. It is a must-have for your vest because BWO hatches are a staple food source for trout during the shoulder seasons and winter months.

What It Imitates

This assortment imitates the adult stage of the Blue Winged Olive or Baetis mayfly. These insects typically feature olive bodies with upright dun-colored wings and range in size from small to tiny. The flies in this selection replicate the profile and color of the naturals as they drift on the surface to dry their wings.

How To Use It

Fish these patterns using a dead-drift presentation on the surface of the water. You should use a long tapered leader and light tippet to minimize drag and avoid spooking wary fish. This approach works best when casting upstream to rising trout in slow to moderate currents.

When To Use It

Use this assortment primarily during the cooler months of spring, fall, and winter. Overcast days with light rain or snow often trigger the most intense Blue Winged Olive activity. These flies are the right choice whenever you see small olive sailboats on the water and fish noses breaking the surface.

Why We Like It

We like this assortment because it removes the guesswork from selecting the right flies for a technical hatch. Rio includes their bestselling patterns and sizes to ensure you have the right tool for the job. It provides high-quality hooks and materials that stand up to repeated use on the water.
