Nice fly Dan! The Hendrickson Mayfly has changed over the years. If anyone is interested, Al Caucci's latest book "The Mayfly Guide" addresses the reclassification of the Ephemerella Genus. The Ephemerella Subvaria and the Ephemerella "X" are the major flies in this classification. Al points out that there are as many as 6 separate subspecies of this mayfly that entomologists have not really identified. All six are rolled into the Ephemerella "X" classification. So as Dan pointed out, there really isn't a Dark Hendrickson with a gray body. The two are the Light (Variant Tannish color) and Dark (Reddish Brown). To makes things more interesting, these can emerge during the same time period. This is one of my favorite hatches to fish on the Upper Delaware River in May.

This was a very helpful/informative video for me. As an amateur at fly tying, I appreciate all of the details and the brief history given.
Nicely done! 👍🏻👍🏻
