Mamestra brassicae, commonly known as the cabbage moth, is a nocturnal moth found across Europe and Asia. It has a wingspan of 34-50 mm, with distinct brown and gray patterned wings. Its larvae, known as cutworms, are significant agricultural pests, feeding on cabbage and other cruciferous plants.

Mamestra brassicae, commonly known as the cabbage moth, is native to Europe, North Africa, and parts of Asia. It is found across a wide geographical range that extends from the British Isles and Scandinavia in the north to the Mediterranean region and the Middle East in the south, reaching as far east as Central Asia.

The cabbage moth typically inhabits temperate regions where it thrives in environments with moderate climate conditions. It is found in agricultural areas, gardens, and grasslands where host plants, primarily from the family Brassicaceae, are plentiful. These areas offer the necessary resources for feeding and reproduction.

Mamestra brassicae is a polyphagous species, meaning it feeds on a variety of host plants, although it shows a preference for cruciferous plants such as cabbages and broccoli. The moth's larvae are significant agricultural pests, as they can cause extensive damage to crops. The species has adapted to exploit cultivated agricultural ecosystems, where its preferred hosts are often grown in abundance.
