The Hendrickson Dark fly pattern is perfect for imitating dark bodied mayfly duns. Fish, especially trout and bass, love to eat mayflies. This fly pattern is a great addition to your fly collection because it imitates such a vast amount of mayfly hatches.
When fishing with this fly, treat it like any other dry fly pattern. You don’t have to worry about it landing perfect on the water. Fish have come accustomed to biting flies that are sitting sideways as the naturals are easily blown over by the wind.
Cast this fly in still water or slow-moving water. Keep your line tight and jerk up at the sign of a strike. Adding a little flotant will help to keep the fly on the surface.
