Cinygmula ramaleyi
(Small Western Gordon Quill) Mayfly Nymph
View 9 Pictures
This nymph is almost definitely the same species as
this dun
, which hatched from a nearly identical nymph from the same collection.
Collected

from
Nome Creek
in
Alaska

Female
Maccaffertium vicarium
(March Brown) Mayfly Spinner
View 7 Pictures
I collected this mayfly on the same trip as
a male
of the same species. They are
Maccaffertium vicarium
mayflies of the type formerly known as
Stenonema
fuscom
, the "Gray Fox."
Collected
May 28, 2005

Namekagon River

Female
Epeorus
(Little Maryatts) Mayfly Dun
View 7 Pictures
This dun comes from the same location, and is about the same size, so is presumably the same species as
this male spinner
.

Rhithrogena impersonata
(Dark Red Quill) Mayfly Nymph
View 6 Pictures
This 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.

Heptagenia pulla
(Golden Dun) Mayfly Nymph
View 8 Pictures
Like 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.
