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.
