Midge / EmergersBarr's Micro Emerger
The Barr's Micro Emerger is a small, highly effective fly that mimics emerging midges in their most vulnerable state. Designed by John Barr, it's a great choice when fish are selectively feeding on midges just below the surface.

Overview
Designed by John Barr, this slim emerger pattern is a minimalist fly built to ride just below the surface during mayfly hatches. It's tied on a curved emerger hook with a sparse dubbing body, a fine shuck made of Antron or Z-lon, and a small tuft of CDC or synthetic for the wing. There's no bead or hackle—just a clean silhouette that imitates an emerging mayfly. The simplicity of materials and proportions makes precise thread control essential when tying.

Presentation
Fish it in the surface film or just below the surface. A slow, steady retrieve can be particularly effective.
When to Use
Use this fly when you observe fish feeding on emerging midges.
Water Type
It can be fished in both stillwater and moving water situations.
Rigging Suggestions
This fly can be fished alone or as part of a multi-fly setup. When fishing a multi-fly setup, consider using the Barr's Micro Emerger as your top fly.
