I agree with Steve's comments below and this appears to be the best example image that we currently have in the guide.

7369 – Xanthorhoe packardata?
I understand that dissection is needed to separate the two but note the sharp tooth pointing inwardly into the red band on the pm. line near the costal margin. Several BOLD images show this for
packardata
but none for
labradorensis
. This trait also agrees with pinned images at Canadian Biodiversity Information Facility (CBIF). Compare both
here
. Your example also shows an outwardly pointing tooth in the am. line near the costa, also is shared by some pinned examples of
packardata
.
Edit: Just noticed another difference. The pm. line tends to be more obviously doubled with the area between the lines more pale then the area beyond.

X packardata
Here are my notes on the two species:
X. packardata—a note in the USNM (from Ferguson?) says that this species is indicated by short antennal setae in males. The am band is darker and the median is less reddish and the moth overall is grayer.
A note at AMNH presumably left by Rindge says…
“male antennae:
labrdorensis—fasciculate
gynandrata—ciliate
packaradata—simple”
I assume gynandrata is a synonym of packardata. Under the scope the sensillae of labradorensis are bunched and longer than the antennal shaft is wide. In packardata, the sensillae appear to be uniformly distributed on the underside and they are shorter than the width of the antennae.

Don Lafontaine has noted that
Don Lafontaine has noted that X. labradorensis males have antennal segments double bifasciculate and X. packardata males have antennae simple, ciliate. I have seen this on all the males I've dissected. I would love to know if Steve Nanz's observations hold true.
