The Northern armyworm, Oriental armyworm or Rice ear-cutting caterpillar (Mythimna separata) is a moth of the Noctuidae family. It is found in China, Japan, South-east Asia, India, Eastern Australia, New Zealand, and some Pacific Islands. They term “Armyworm” is used because of their habit to spread out in a line across a lawn or pasture, and slowly “marching” forward, meanwhile consuming the foliage they encounter.

The wingspan is 35–50 mm. The moth flies from January to April depending on the location.
The larvae feed on a range of agricultural plants like Zea mays, Sorghum bicolor and Oryza sativa and are thus considered a pest.
Infestations
China experiences periodic outbreaks of northern armyworm infestation.[1] The outbreak in 2012 was particularly severe.[2]
