I posted the original topic that Bamboozle alluded to, and after a lot of experimentation I found that the simplest and most effective pattern is just a size 12 hook with a a black dubbed body and just some fluorescent yellow foam in the back. Use some red floss of thread for the head and tie in two turkey quill wings that are the length of the body. This looks very much like the lightning bug and floats well in flat water. If you are going to fish rougher water, add some hackle to the front 1/3. I've taken many brookies and browns on this fly this summer. It also is a great bluegill fly, even during the day.
