Trico Thorax

The Trico Thorax is a classic small dry fly pattern trusted by anglers targeting selective trout during delicate mayfly hatches. Known for fooling large, wary fish, this proven pattern offers a realistic silhouette and low-profile presentation that excels in technical fishing situations.

Especially effective on tailwaters and stillwaters, the Trico Thorax is a must-have during trico and small mayfly hatches when trout feed aggressively on the surface. Keeping a range of sizes available helps accurately match changing hatch conditions throughout the day.
