Trichoplusia ni
Cabbage Looper Moth, Cabbage Looper
The cabbage looper (Trichoplusia ni) is a noctuid moth whose larvae are significant agricultural pests of cruciferous vegetables and other crops. The species derives its common name from the larva's distinctive looping locomotion, caused by having only two pairs of abdominal prolegs rather than the typical four. Adults are medium-sized brownish moths with a silvery figure-eight or Y-shaped marking on the forewings. The species has a broad distribution and is particularly problematic in commercial vegetable production due to its polyphagous feeding habits and capacity for rapid population growth.
