Callibaetis – Thorax
The Callibaetis Thorax is a proven dry fly pattern designed to imitate adult Callibaetis mayflies commonly found on lakes, ponds, reservoirs, and slow-moving trout waters. Featuring a distinctive upright thorax-style wing, this pattern offers improved visibility while maintaining the realistic silhouette and natural presentation that trout expect during a hatch.
Callibaetis mayflies are among the most important food sources on stillwaters throughout the West, often producing extended hatches and consistent surface feeding activity from spring through fall. The Thorax style rides naturally on the surface film, effectively imitating freshly emerged adults that trout eagerly target.
Whether you’re matching an active hatch or prospecting likely feeding areas, the Callibaetis Thorax provides a reliable option for surface fishing in stillwater environments.

This fly performs well on slow-moving waters. The thorax wing stands out on the surface and trout take it consistently during early spring hatches. Easy to tie and matches the natural mayfly well.
Virginia Lewis –
I’ve used this pattern on a few lakes and it’s one of the most effective dry flies for surface feeding trout. The presentation is natural and the fly stays on the surface film without sinking.
Lillian Robertson –
Great for matching active hatches. The upright thorax design gives it a realistic look and trout are quick to react. Works well in stillwater conditions during late spring and early summer.
Wanda Davies –
Felt like a solid choice for stillwater fishing. It’s not flashy, but it’s effective and realistic. I caught several trout on it during a quiet morning on a reservoir.
Donna Lewis –
Used it during a spring hatch and saw multiple takes. The fly floats naturally and looks like a real mayfly. A reliable pattern for surface fishing in calm waters.
