When trout feed on spent spinners they do it with comfort. These dead mayflies will not fly away or move. The rise is slow and easy going, often in an head-and-tail style. Many anglers find it diffucult as the fish turns selective during times when hundreds of Spent Spinner’s lies across the surface. To succed and maybe hook the trout of your life, you will need to observe how the fish moves, were it feeds and make a good presentation. But as important is that you use a good imitation. The fish has alot of time to observe the fly and will not take a poor imitation.
