What is a "fall armyworm"?

A fall armyworm is a destructive pest that primarily affects crops such as maize, rice, sorghum, and other grassy plants. It is the larval stage of a moth species. Fall armyworms are named for their behavior of forming large groups and moving in an "army-like" manner, causing significant damage to vegetation in their path. They have a voracious appetite and can rapidly devour crops, leading to yield loss and economic impact on agricultural communities. Fall armyworms are highly mobile and can quickly spread to new areas, making their control challenging.
