Hendrickson Mayfly Pattern
Ephemerella subvaria Dun – Hendrickson
The Hendrickson hatch is one of the first prolific mayfly hatches of the season, often corresponding with opening day of trout season. Females have dull brown bodies with lighter colored legs and wings of brown or brownish gray. Males, slightly smaller in stature, have more pinkish brown bodies, lighter colored legs, and darker wings, tending toward a slate gray.
Hendrickson Duns generally emerge in mid-afternoon when temperatures are ideal, but can also hatch during miserable cold and wet weather.

Continue to cover the materials up to and just short of the hook eye to keep an even taper to the body.
Tie in the Turkey Wing material for the body.
Twist the material as you wrap it forward. Now wrap your thread over the body working towards the tail in one direction and reversing the direction as you come back to the endpoint to get a Criss-cross pattern over the body. This will make the fly more durable.

Tie in your Hi-vis wing material, we will trim it later.
Wrap your hackle forward towards the hook eye, but be sure to put a couple of wraps behind the wing and then move forward.
Tie of the hackle and whip finish the fly.

Trim the hackles underneath the fly to make sure the fly sits right on the water.
