The cabbage looper (Trichoplusia ni) is a member of the moth family Noctuidae. It is found throughout the southern Palaearctic ecozone, all of North America, parts of Africa and most of the Oriental, parts of Europe (primarily South Europe) and Indo-Australian region. In the United Kingdom, where the adult is primarily a (sometimes numerous) immigrant but breeding is rare, the species is also known as the Ni Moth. The name derives from the forewing marking, which resembles the lowercase Greek letter ni.
