The fall armyworm (Spodoptera frugiperda) is a species in the order of
Lepidoptera and is the larval life stage of a fall armyworm moth. The term
鱗翅目 幼蟲的
"armyworm" can refer to several species, often describing the large-scale
invasive behavior of the species' larval stage. It is regarded as a pest and
can damage and destroy a wide variety of crops, which causes large economic
damage.
Because of its propensity for destruction, the fall armyworm's habits and
possibilities for crop protection have been studied in depth.
It is also a notable case for studying sympatric speciation, as it appears
同域的(?)
to be diverging into two species currently.

Another remarkable trait of the larva is that they practice cannibalism.
