In 1964 Fran Betters created the now famous, Ausable Wulff.
“After years of fishing the AuSable and other Adirondack Streams, and after studying numerous insects, I had noticed a particular curiosity relating especially to the large stonefly and mayfly nymphs in the rivers of the Adirondacks,” Betters wrote in his book, “Fly fishing and — fly tying and pattern guide.” “They seemed to have a slight rusty orange coloration in the thorax and some red in the heads of the flies. I thought that this might be characteristic of flies on these streams due to the mineral content of the streambeds.”
