This common name refers to only one species.

Mayfly Species Ephemerella subvaria

These are very rarely called Beaverkills.
The Hendrickson hatch is almost synonymous with fly fishing in America. It has been romanticized by our finest writers, enshrined on an untouchable pedestal next to Theodore Gordon, bamboo, and the Beaverkill.

The fame is well-deserved. Ephemerella subvaria is a prolific species which drives trout to gorge themselves. Its subtleties demand the best of us as anglers, and meeting the challenge pays off handsomely in bent graphite and screaming reels. Ours may be the sport of gentlemen, but the gentleman may drool a little on his tie when he thinks of this hatch-to-come after a dismal fishless winter.
