These are sometimes called Slate Cream Duns.
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 very rarely called Slate Cream Duns.
This is one of the two most common Western species of Epeorus
, and its spinner falls can be important.
