Natural Habitat

Vegetation and soil in gardens, farms, and disturbed areas, especially where potato-family plants grow.

Diet & Feeding

Larvae and adults primarily eat foliage of potato, tomato, eggplant, and other Solanaceae. Heavy infestations can completely defoliate plants.

Behavior Patterns

Adults overwinter in soil, emerge in spring, and females lay yellow egg clusters beneath leaves. Larvae pass through four stages, then drop into soil to pupate; multiple generations may occur annually.

Risks & Benefits

It is a significant agricultural pest and readily develops resistance to insecticides. It has little direct benefit to humans, though it is part of food webs as prey for birds and predatory insects.
