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.
