This week’s Throw Back Thursday Fly is the Rosborough Casual Dress Nymph.
I found the fly on display at the International Federation of Fly Fishers Museum in Livingston, MT and took this picture of the Rosborough Casual Dress Nymph through the glass display in a dark room. I think it turned out quite well. It was one of several flies in the collection of Polly Rosborough. It’s is one of several flies in a display entitled Polly’s Proven Killers.
The Rosborough Casual Dress Nymph can be used to imitate a mayfly, stonefly, or caddis. Polly tied the fly and fished it on the Upper Deschutes River in 1960.
Polly lived in Chiloquin, Oregon and his home river was the Williamson River.
Ernest H. “Polly” Rosborough (1902 – 1997) tied a large variety of flies but is probably best known as an author of Tying and Fishing the Fuzzy Nymph (1969).
