Pale Morning Dun Dry Fly

Fishing Tips

In fly fishing, the term "Dun" refers to the sub-imago or adult stage of certain mayflies. Mayflies go through a series of developmental stages from egg to nymph, to dun (sub-imago), to spinner (imago). The dun stage is characterized by the insect's emergence from the nymphal shuck and the process of drying and hardening its wings. During this stage, the mayflies are highly vulnerable to predatory fish as they are unable to fly and are often found floating on the surface of the water. As a result, they are prime targets for hungry fish, making the dun stage an important time for fly anglers to imitate the insect with dry flies.
