Pale Morning Dun Thorax

The Thorax PMD represents an adult mayfly at rest, with a natural leg/spread-wing profile. The hackle wrapped horizontally around the thorax helps the fly sit low on the water, imitating the natural stance of a freshly emerged dun.

History:
The thorax-style dry fly was championed by anglers like Vince Marinaro in the mid-1900s, who emphasized naturalism over tradition. This version of the PMD works particularly well in clear water with finicky fish.
