These days there are so many reasonably simple fly patterns that work well but have no soul or appeal to fly tiers. Pat Dorsey took a simple combination of materials and created a fly that is durable, quick, and fun to tie, and it not only gets the job done, but it also looks good doing it.
Based off the success of his remarkable Top Secret Midge pattern, Dorsey took a familiar route to alter that pattern slightly to create this effective Baetis imitation.
The beauty of this fly is that it is tied from very commonly available materials-for the most part, albeit with some necessary modern-day substitutions-and it is straightforward to tie.
