Like most common names, "Little Maryatt" can refer to more than one taxon. They're previewed below, along with 8 specimens. For more detail click through to the scientific names.
These are often called Little Maryatts.
There is remarkable variety of form and color within this prolific genus of fast-water mayflies. Different species are found across the country, and several cause good hatches. Fly anglers are likely to encounter the lesser species on occasion, too.
The best Epeorus
hatch in the East is Epeorus pleuralis
, the famous Quill Gordon, the first abundant large mayfly hatch of the year. Epeorus vitreus
comes a little later and is important in both the East and Midwest.
In the West, Epeorus longimanus
dominates in fast, high-altitude streams, while Epeorus albertae
inhabits slower and lower waters.
These are sometimes called Little Maryatts.
These are very rarely called Little Maryatts.
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.
