Plusiina
Plusiina is a subtribe within the subfamily Plusiinae of the moth family Noctuidae. Members are commonly known as loopers or semiloopers due to their distinctive larval locomotion. The subtribe includes economically significant agricultural pests such as Rachiplusia nu and Chrysodeixis includens, which cause defoliation damage to soybean and other crops. Larvae are characterized by having three pairs of prolegs and a looping gait, distinguishing them from true geometrid loopers which possess only two pairs.
