Dry fly tie on Hanak 390bl hook and Hends materials. This fly is made from grey thread and CDC wings with hare ears 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 example, on the Adirondacks and Québec rivers size 12 and 14 worked well, but on some European rivers and Alberta Old Man river size 16 and 18 were the best
