Moved
Moved from c-nigrum/dolosa complex. I distinctly recalled noticing that one of the c-nigrum/dolosa from this night was noticeably smaller than the other. I don't know the size of each square on our sheets, but the FW of this one is about five squares long compared to four for the other. That should make this one dolosa and the other c-nigrum.

Sheets
My recollection is that each square is 4 mm, however, your mention of sheets also reminded me that I believe both sets are at your house! I was thinking of putting one or more into action soon!

X. dolosa
The grid is a 4 mm square. The FW of this moth is ~21 mm, too big for X. c-nigrum.

Ah, should have subscribed to this image
You wouldn't have had to text me about it. Problem is I'm not certain the basement lock is unlocked. Hopefully that won't be an issue!

4mm seems about right, as that would make the smaller one come out to a FW length of ~16mm, perfect for c-nigrum according to the guide page, while this one should have something like a 40mm WS, right where dolosa should be.
