The square-spot rustic (Xestia xanthographa) is a moth of the family Noctuidae. It is found in Africa, Europe, Northern Asia (excluding China) and North America. The species is quite variable in appearance, the forewings occurring in various shades of grey or brown, with melanic forms common in parts of its range. The best identifying feature is the large, pale, squarish stigma which gives the species its common name. The hindwings are pale to dark grey with a whitish fringe. The wingspan is 30–40 mm.
