This specimen was photographically identified by David W Droppers as Lobophora magnoliatoidata; however Ferris et. al. notes these two names as synonymous for the same species, and there is a note in BugGuide: "Lobophora magnoliatoidata have also nearly identical DNA matches to nivigerata - probably same species". Both BugGuide and Moth Photographer's have separate entries with different Hodges numbers for the two. I chose to put this under nivigerata for no reason other than that is by far the most common selection in iNat.
