Hugh,
You know I have said that I hate to make a mistake, but guess if you don’t
stick you neck out you don’t learn. On the missed unimoda, I even quickly
checked a few images of saucia before posting, but obviously not carefully
enough. I forgot to look for the 7 short black mark pattern that is noted
at BG that I even quoted in a previous post. Looking at the two species
now, the antennae seem to be different. A bad miss on my part.
Never would have thought violacea. My comment about a few viatical
overwinter comes from seeing January and February records at BG by Ken
Childs. Perhaps his too are violacea. Here are links to those sightings,
January 28, 2013, https://bugguide.net/node/view/756120; and February 7,
2013, https://bugguide.net/node/view/756122. They could be the same
individual, but the PM line looks different though lighting is different.
Thoughts to species?
I will go back and look at all my late “viatical” to see if there were
possibly others. I have two small hollies (less than 10’ tall and skinny)
that I think are American that are not too far away. I would collect a few
to verify. Never done this before, so will need some instruction.
My profound thanks for pointing out my errors.

Michael,
Nice set of images. I believe your first two are incorrectly IDed. #1 is
Lithophane unimoda and #2 is most likely M. violacea. M. viatica generally
cannot over-winter, while violacea does so regularly. This moth also looks
too suffused with violet to be viatica. If you would like to confirm, you
could collect a few and send and I will compare them to the collection at
USNM.

Overall, it has been a cold week, at least for much moth activity, with
the except of Sunday and Monday nights, the 16th (10 species and 22
individuals) and 17th (15 species and 148 individuals), for cumulative
total of 16 species. I thought the 17th would be a little better with a
high of 67 F, but the temps dropped too fast and there were no SB runs in
the 60’s. Highlights included a fresh Armyworm Moth, last seen on December
25, 2019 (there are Tennessee records in all months except January); the
return of the overwintering Lithophane ‘near disposita’, last seen on
November 29, 2019; and six species of Lithophanes in one night including a
new species for HC, L bethunei (Bethune's Pinion Moth).
The rest of the month is mainly projected cool to cold and the extended
forecast for my area for March is for much below normal temperatures. The
bright side of a cool spring is that it does not go too fast and you get
more time to do spring things.
