Sprout Baetis
The Sprout Baetis is a top-tier BWO emerger for trout, especially during cold-weather blue-winged olive hatches. It has a sparse, natural look that excels on technical rivers where trout ignore bulky or overdressed mayfly emergers.

How to Rig It
Fish it alone to sipping trout or as a trailer behind a visible BWO dry.

Deliver long drag-free drifts in the exact seam where fish are quietly rising.

The tiny CDC bubble wing and slim olive body make it look alive without too much material.
History
Charlie Craven's Sprout Baetis became widely respected as anglers searched for better BWO emerger patterns for educated trout.
Pro Tip
Keep a dedicated BWO box with several shades of olive because trout can be extremely tone-sensitive in cold clear water.
