Dry fly tie on Hanak 130bl hook and Hends materials. This fly is made from peacock hearl and CDC wings with peacock dubbing.
This particular fly pattern works well in the morning hatch but the best time is in the evenings and on cloudy days hatch, the target species are trout and grayling.
The best size is depending on the size of the insects that are found on the river. For this particular fly I would recommend size 18 and in some situations size 16.
