Notes:This fly was first tied in 1982 for Colorado's Frying Pan River, by Mark Engler.
It imitates the larger midges that get trapped in the shuck for extended periods. It is more a style of midge emerger than a
specific pattern. Thread and dubbing can be chosen to match the color of any natural, the most popular colors being Olive, Black,
Dark Brown, Gray, and Rust. The WD stands for "Wood Duck", of which each pattern uses this material for the tail and
wingcase. The original WD-40 had an olive thread body and a muskrat thorax. There are some substitions in which the Wood Duck
wingcase has been replaced by Krystal Flash or Razor Foam but this would really make it something other than a WD, wouldn't it.
Another interesting variation is to substitute the dubbed abdomen with a glass bead or two. You can also easily incorporate legs
to the pattern by utilizing the butt ends of the wingcase rather than trimming them flush to the shank. | ||
