The same specimen is illustrated in the photos at center and right.
My initial identification of Scythris limbella was based
on Internet sources, and subsequently checked against specimens in the Canadian
National Collection in Ottawa. From my searches, this species appears
mainly to be illustrated from Europe. The North American occurrences
appear to have been considered different species, and more recently recognized
as being the same as the European species.
Scythris limbella has a yellowish buff forewing, with
dark brown to black markings. A brownish shade runs the length of the
costa. There are several dark blotches in the yellow-buff part of the
wing, the most consistent being a somewhat square patch near the midpoint of the
inner margin, and the dark-brown to black at the apex. Other dark markings
are located where one would expect the antemedial and postmedial lines, and may
appear as blotches, or as small groups of dark streaks, or sometimes even as
zigzag lines. Note the upturned "tail" of the ends of the wings
when the moth is resting with wings closed, most evident in the center photo
above. The hindwing is brownish. This is a small moth, with wingspan
less than 1.5 cm.
I have no information on the life cycle of Scythris limbella
except that the larva is reported to feed on lambsquarters (Chenopodium).
My records to date for Scythris limbella (each date
