How to Tie a Thorax-Style Sulphur Dun

Producer: Tim Flagler

Says videographer Tim Flagler: “In Vince Marinaro’s book A Modern Dry-Fly Code he provided detailed instructions for tying a thorax-style dry fly. Few other dry fly patterns rival it’s ability to fool hyper-selective feeding trout. It’s finely shaped wings, tail fibers splayed at 90 degrees and criss-cross hackling all contribute perfectly to the fly’s look and function. They also make it rather difficult to tie.”
