Cabbage Moth

Mamestra brassicae

The cabbage moth is primarily known as a pest that is responsible for severe crop damage of a wide variety of plant species. The common name, cabbage moth, is a misnomer as the species feeds on many fruits, vegetables, and crops in the genus Brassica. Other notable host plants include tobacco, sunflower, and tomato, making this pest species particularly economically damaging. Source
