The lesser armyworm (Spodoptera exigua) is usually olive-green in colour, but yellow or darker individuals may be encountered (darker forms appear during overcrowding). A characteristic pink line or spots are found on the sides of some individuals. The moths have characteristic orange spots on the forewings, while eggs are also covered by anal hairs. Pupae are also found in earthen cells (not illustrated).
