This pattern is based on the Shuttlecock Buzzer patterns I have seen published in Czech books and websites. I typically tie these in smaller sizes for imitating emerging midges on my local trout streams. My favorite sizes are 16-22. Black, Olive, and Grey are all productive colors. This fly can be tied much larger when fishing chironomid hatches on stillwaters. When tying this fly in larger sizes it helps to add 1 or 2 feathers to the wing.
