This week’s Throw Back Thursday Fly is Polly Rosborough’s Fledermouse Nymph.
I recently had a customer request several of these flies and thought it would be a good candidate for a TBT post.
Here is a close-up of the nymph.
Ernest H. “Polly” Rosborough (1902 – 1997) lived in Chiloquin, Oregon and his home river was the Williamson River.
Polly tied a large variety of flies but is probably best known as an author of Tying and Fishing the Fuzzy Nymph (1965).
I didn’t know much about the Fledermouse Nymph, but it’s one of the flies Polly wrote about in Tying and Fishing the Fuzzy Nymph (1965). Four years later, Orvis published the second printing, which is the copy I have.
I think the fly is “old school”, meaning the it only uses natural materials from muskrat or beaver, mink, and jackrabbit (I substituted Hare’s Ear) for the body and collar. Two wings are stacked using barred teal and barred brown widgeon. I’ll bet most of you wouldn’t have these materials on hand to tie the fly. Turns out, I do.
Using all these materials makes a brown and grey fly from body to wing and head.
To describe the fly in his book, Polly begins “This nymph is probably as near all-purpose as it would be possible to devise. It also nearly embodies all the principles of the old “Near Enough” dry fly that it can be used with at least average success in all waters at all times.“
