Andersons Bird of Prey Caddis is a highly adaptable caddis emerger pattern designed to imitate both the pupa and emerger stages of a wide range of caddis species. Built with a buggy dubbed body, soft partridge fibers, pearl flash ribbing, and a peacock thorax, the fly produces constant movement and a highly realistic silhouette in the water. The soft hackle and natural materials pulse naturally in the current, making it especially effective during active caddis emergences when trout are feeding just below the surface film.
