Like most common names, "Lady Beaverkill" can refer to more than one taxon. They're previewed below, along with 6 specimens. For more detail click through to the scientific names.
These are sometimes called Lady 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.
These are very rarely called Lady Beaverkills.
This species, the primary "Sulphur" hatch, stirs many feelings in the angler. There is nostalgia for days when everything clicked and large, selective trout were brought to hand. There is the bewildering memory of towering clouds of spinners which promise great fishing and then vanish back into the aspens as night falls. There is frustration from the maddening selectivity with which trout approach the emerging duns--a vexing challenge that, for some of us, is the source of our excitement when Sulphur time rolls around.
is one of the two species frequently known as Sulphurs (the other is Ephemerella
dorothea). There used to be a third, Ephemerella rotunda
, but entomologists recently discovered that invaria
are a single species with an incredible range of individual variation. This variation and the similarity to the also variable dorothea
make telling them apart exceptionally tricky.
As the combination of two already prolific species, this has become the most abundant of all mayfly species in Eastern and Midwestern trout streams.
