The triple-spotted clay (Xestia ditrapezium) is a moth of the Noctuidae family found in most of Europe, northern Turkey, northern Iran, Transcaucasia, Caucasus, central Asia, from the Altai to Ussuri, Amur, Kuril Islands, northern Mongolia, Tibet, China, Korea, and Japan.

The wingspan is 35–47 mm. The forewing is darker than in Xestia triangulum Hufn., a smooth vinous brown; the dark markings are not so black; the hindwing is distinctly yellowish-tinged.[1]
