Little black stoneflies are a perfect late winter early spring dry fly. This video shows Hans Stephenson using a great technique for creating a really impressionistic wing. I have a couple tied up already for the upcoming season. I’ve tied them small, 18 and 20 to match the size of the little stones. I might be able to get away with 16 as well. The black CDC is nice and buggy. I would personally keep the CDC a bit longer and trim it streamside if necessary. The look if the fly with the untrimmed CDC looks awesome.
