The term "armyworm" relates to the behaviour of the larvae, which often spread out in a line across a lawn or pasture, and slowly "march" forward en masse, consuming the foliage they encounter.[1] The larvae feed on a range of agricultural plants, such as pineapples (Ananas comosus), sweet potatoes (Ipomoea batatas), alfalfa (Medicago sativa) and various grass species (Poaceae), and are thus considered a pest.
