The fall armyworm is a strong flier, and disperses long distances annually during the summer months. Thus, in the USA it is recorded from virtually all states east of the Rocky Mountains. However, as a regular and serious pest, its range tends to be mostly the southeastern states.

Life Cycle and Description

The life cycle is completed in about 30 days during the summer, but 60 days in the spring and autumn, and 80–90 days during the winter. The number of generations occurring in an area varies with the appearance of the dispersing adults. The ability to diapause is not present in this species. In northern areas, where fall armyworm moths do not appear until August, there may be but a single generation. The number of generations is...
