The cabbage moth has a wide geographic distribution across parts of Europe and Asia ranging from about 30°N to 70°N in latitude. This geographic range is within the Palearctic region, which includes parts of Europe, Asia north of the Himalayan Mountains, and Africa north of the Sahara Desert. As many host plants are both endemic or domesticated in various parts of this region, the moth is able to successfully thrive in nearly all parts of this region due to local adaptation (Masaki).
