[2] The adoption of the hairwing patterns that eventually became the Wulff dry fly style began in the late 1920 in several locations.

Both Wulff and Quackenbush made the modifications because the Fanwing Royal Coachman proved too flimsy and fragile on rough water.

[6] Angler and writer John Gierach believes the Royal Wulff is one of the most popular dry patterns over the last half century.

[8] Early in the 20th century, Theodore Gordon once was of the opinion that the Royal Coachman resembled some form of flying ant, while in the 1950s, Preston Jennings, a noted fly tier and angler thought the Royal Coachman resembled Isonychia mayflies.

The Royal Wulff is a dry fly and the wing is typical tied with white bucktail or calf tail.
