A hook, thread body tied in a fashion to create a rib, scant dubbing for a thorax consisting of squirrel and ice dub., a turn or two of partridge hackle and it's done.
When the fly is placed in the stream that's when the realistic aspects of the fly takes place. The movement of hackles, and when allowed to sit motionless in the current the fly will also look alive. Translucent is a key. The little bit of dubbing with one or two ice dub fibers glimmering form a life like body.
It's no wonder this style of fly has been around for hundreds of years. I can't wait until the time comes when I can drift these flies again.
