Female Epeorus (Little Maryatts) Mayfly DunFemale Epeorus (Little Maryatts) Mayfly Dun View 7 PicturesThis dun comes from the same location, and is about the same size, so is presumably the same species as this male spinner.
Collected May 15, 2007 from Enfield Creek in Treman Park in New York

Heptagenia pulla (Golden Dun) Mayfly NymphHeptagenia pulla (Golden Dun) Mayfly Nymph View 8 PicturesLike most Alaskan mayflies, this one is tricky to identify to the species level. See the discussion section for an informative chat about this one's ID. The current leaning is to call it a fairly immature Heptagenia pulla nymph, but a case has been made for Heptagenia elegantula as well.

Female Leucrocuta hebe (Little Yellow Quill) Mayfly DunFemale Leucrocuta hebe (Little Yellow Quill) Mayfly Dun View 9 PicturesI found this dun on the same piece of stream as a similar spinner, probably of the same species.

Rhithrogena impersonata (Dark Red Quill) Mayfly NymphRhithrogena impersonata (Dark Red Quill) Mayfly Nymph View 6 PicturesThis was the only Rhithrogena specimen in a large sample of nymphs from a small Catskill stream. It looks virtually identical to Rhithrogena impersonata specimens collected in the Midwest, but I didn't get to check the distinguishing features under a microscope.
