Overview

This dry fly uses two contrasting hackles—usually brown and white—wrapped together to increase visibility while maintaining a buggy appearance. Tied on a standard dry fly hook with a thread body and no wing, this pattern is simple but effective. Use high-quality dry fly hackle and avoid overcrowding the front with wraps to maintain a clean silhouette.

Fishing Tips

Season

The Bivisible is most effective from spring through fall when terrestrial insects are prevalent.

Presentation

Cast upstream and let it drift naturally. Use a twitching motion to mimic an insect struggling on the water's surface.

When to Use

This pattern is great to use when no specific hatch is happening and you're searching for feeding fish. It can also be effective during a terrestrial fall.

Water Type

It works well in both stillwater and moving water environments.

Rigging Suggestions

Use a standard dry fly setup with this fly. It can also be used as an indicator fly in a dry-dropper setup.

Visibility & Floatation

The Bivisible is easy to spot due to its contrasting colors. The dense hackle helps it to float high on the water's surface.
