Like most common names, "Western Gordon Quill" can refer to more than one taxon. They're previewed below, along with 7 specimens. For more detail click through to the scientific names.

Mayfly Genus Epeorus

These are sometimes called Western Gordon Quills.
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.

Mayfly Species Rhithrogena futilis

These are sometimes called Western Gordon Quills.
This uncommon and slightly larger species hatches earlier than Rhithrogena hageni, but otherwise is virtually indistinguishable.

Mayfly Species Epeorus albertae

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

For a great and informative discussion of all Epeorus species and other mayflies be sure and read, WESTERN MAYFLY HATCHES by R. Hafele and D. Hughes. They rate all of the western mayflies and they rate the hatch of this genus a 25 out of a possible 45 points based on several rating criterion. They provide insect photos, possible fly patterns and fly presentations. This is a great book.
