Hendrickson Nymph

The Hendrickson Nymph fly pattern is a type of fly used for fly fishing, specifically for imitating the nymph stage of the Hendrickson mayfly, which is a common insect found in many rivers and streams. The nymph stage of the Hendrickson mayfly is an important food source for fish, especially trout.
The Hendrickson-Nymph is typically tied with a curved hook, and the body is made with a combination of natural and synthetic materials to imitate the color and texture of the nymph. The fly also features a tail made of fibers or hackle. A bead head version of this fly can help it sink deeper in the water column.
