The Fall Armyworm moths usually lay the eggs on either side of the leaf. Generally, the eggs take two to three days to hatch in warm tropical conditions. After hatching the young caterpillars move to the maize funnel where they hide during the day and feed on the young leaves.

The caterpillars (larvae) normally grow for 2-3 weeks while feeding on the crops thereby causing great damage. These caterpillars then crawls into the soil whwre they pupate (develops into pupa). The pupal stage lasts for about 1-2 weeks after which it becomes an adult moth.

The female fall army worm can lays eggs  5 days after becoming a moth. This is normally after multiple mating and can live up to three weeks.

The adult moth can fly long distances at night to colonize new areas.
