Identification
The scalloped sallow can be distinguished from similar noctuid by its prominently scalloped wing margins, which give the its . The combination of yellowish-orange forewings with darker markings and pale hindwings, along with the moderate wingspan of 36–44 mm, helps separate it from related Xylenini moths. The late-season period (August–December) also aids identification.
