i was out
fixing the shed yesterday afternoon, reached down to open the door, and say a
mayfly....smallish, maybe a 16.....two tails, mottled tannnish/greyish.....didn't
get a great look
i am assuming it came from the sheepscot across the street Tim-
Given the keys you provided, size #16, 2 tails, mottled tannish/grayish, the
possibilities would seem to be Callibaetis, Leucrocuta,
Maccaffertium, or Rhithrogena.
Callibaetis primarily inhabit still water, and
Maccaffertium
and Rhithrogena are more likely
be a bit larger than #16, so my best guess would be
Leucrocuta.
Leucrocuta species are variously
referred by common names of Graywinged Yellow Quill, Little Evening Sulphur,
Little Evening Yellow, Little Pale Evening Dun, Little Yellow Quill, Pale
Evening Dun, and Small Graywinged Yellow.
In Maine, you have Leucrocuta aphrodite, L. hebe, L.
macullipenis, L. minerva, and L.
walshi.
Incidentally, all of this information is available on my website,
www.FlyfishingEntomology.com. The potential genera
were determined with the
Identifying Adult Mayflies screen, by selecting # of
tails (2), Body length: (07 mm. #16), Fore wings: (marked/mottled), Geographic
location: (USA:NE). The common names were determined with the
Names Query screen by keying
Leucrocuta into the box for Scientific Names containing.
The Leucrocuta species in Maine
were determined with the
N. American Mayfly Distribution screen by keying ME
into the entry box for USA (state).
