Callibaetis – Thorax

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. This variation features a distinctive upright wing profile rather than traditional side-mounted wings, creating a highly visible silhouette while maintaining a realistic presentation.

Callibaetis mayflies are among the most important hatches on stillwaters throughout the West, often producing consistent surface feeding activity from spring through fall. The Thorax style rides naturally on the surface and effectively imitates freshly emerged adult mayflies that trout readily target.

Whether fished during an active hatch or as a searching pattern, the Callibaetis Thorax is an essential fly for anglers pursuing trout on stillwater fisheries.
