Male Epeorus (Little Maryatts) Mayfly SpinnerMale Epeorus (Little Maryatts) Mayfly Spinner View 10 PicturesThis spinner and hundreds of others like it were dancing over the road through a very narrow valley carved by a tiny, steep tributary of the trout stream I was fishing. I got strange looks from a few passers-by, standing around on the road with a butterfly net...
Collected May 9, 2007 from Unnamed trib of Factory Brook along 42a in New York

Male Epeorus pleuralis (Quill Gordon) Mayfly SpinnerMale Epeorus pleuralis (Quill Gordon) Mayfly Spinner View 10 PicturesA few days earlier I photographed this same specimen as a dun. The changes between dun and spinner seem particularly dramatic in this species.

Male Epeorus (Little Maryatts) Mayfly SpinnerMale Epeorus (Little Maryatts) Mayfly Spinner View 10 PicturesI collected a female dun on the same day that probably belongs to the same species as this spinner.

Male Epeorus (Little Maryatts) Mayfly DunMale Epeorus (Little Maryatts) Mayfly Dun View 12 PicturesI hoped this dun would molt into a spinner for a positive ID, but it didn't. My best guess is Epeorus dulciana, but that's only because that's the smallest western Epeorus species, and this specimen is smaller than any of the others, with a body length of 5.3 mm (although it would be longer as a spinner) and a wing length of 8.5 mm.

It was collected at the same time as a similar-sized female dun.
Collected July 5, 2017 from the South Fork Sauk River in Washington
