Female Stenacron interpunctatum (Light Cahill) Mayfly DunFemale Stenacron interpunctatum (Light Cahill) Mayfly Dun View 6 PicturesThis is a fairly small late-season female Stenacron dun.

Female Leucrocuta hebe (Little Yellow Quill) Mayfly SpinnerFemale Leucrocuta hebe (Little Yellow Quill) Mayfly Spinner View 6 PicturesI found this spinner on the same piece of stream as a similar dun, probably of the same species.
Collected September 19, 2006 from Mystery Creek #43 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.

Cinygmula (Dark Red Quills) Mayfly NymphCinygmula (Dark Red Quills) Mayfly Nymph View 7 PicturesThis very strange nymph appears to be undoubtedly Cinygmula, yet it lacks the telltale protruding mouthparts that usually make that genus so easy to identify.

Male Epeorus vitreus (Sulphur) Mayfly DunMale Epeorus vitreus (Sulphur) Mayfly Dun View 4 PicturesThis is my favorite mayfly from 2004, and it appears on my popular Be the Trout: Eat Mayflies products. Check them out!

Its identification is really up in the air. It might be a late-season vitreus dun but it may very well be one of the more obscure species in that genus.
Collected September 2, 2004 from the Beaverkill River in New York

Female Cinygmula ramaleyi (Small Western Gordon Quill) Mayfly DunFemale Cinygmula ramaleyi (Small Western Gordon Quill) Mayfly Dun View 7 PicturesThis dun is almost certainly of the same species as this nymph, as it hatched in my cooler from a nearly identical nymph.
