The Armyworm (Spodoptera frugiperda) is a species in the order of Lepidoptera and is the larval life stage of a fall armyworm moth. It is regarded as a pest and can damage and destroy a wide variety of crops, which causes large economic damage. Its scientific name derives from frugiperda, named because of the species' ability to destroy crops. Because of its propensity for destruction, the fall armyworm's habits and possibilities for crop protection have been studied in depth.
Eggs are spherical and creamy in color and are laid in a group covered over with grey hairs.
The caterpillars are light green with yellowish-white lateral and dorsal stripes in the early stage and later become dark brown or grayish-green in color with a crescent (Semi-circular) shaped black spot on the side of each segment.
