Habitat Preferences of Lawn armyworm Through Different Life Stages
The eggs of lawn armyworm are predominantly found on the underside of leaves, making them somewhat sheltered and concealed from predators. Given this preference for leafy locations, when searching for the larval stage, one should inspect the host plants upon which lawn armyworm commonly feeds, such as rice or maize. The caterpillars are typically found amidst the foliage, often on the leaves where they voraciously feed. For the pupal stage, searching the soil or leaf litter near host plants would yield the best results, as lawn armyworm caterpillars burrow to pupate. These pupae are generally ensconced in a cocoon just below the soil surface or within the upper layers of detritus. Adults prefer to rest in areas with dense vegetation during daylight hours, emerging at night to feed and lay eggs.

How and Where Can You Find Lawn armyworm at Different Life Stages
Egg Eggs of lawn armyworm are typically laid in clusters on the underside of leaves. Find them by inspecting the leaves of host plants, especially in the evening.
Larva Larval lawn armyworm can be found by looking on or near their food sources, such as crop leaves or stems. Look for signs of feeding damage as an indicator.
Pupal Pupal lawn armyworm usually develops in the soil or in hidden places near host plants. They can be found by gently digging around the base of the plants or by searching under leaf litter.
Adult Adult lawn armyworm are attracted to light and can be located by setting up light traps after dusk. Alternatively, searching for them resting on vegetation during the day can also be effective.
