Cutworm (larva)

Natural Habitat

Found in agricultural fields, gardens, lawns, and disturbed areas, typically burrowing in the top layer of soil or under debris during the day.

Diet & Feeding

Primarily herbivorous, feeding on the stems and leaves of young plants, often cutting them off at or below the soil line. They are known to feed on a wide variety of vegetables, grains, and ornamental plants.

Behavior Patterns

Nocturnal feeders, they curl into a tight C-shape when disturbed. They spend their days hidden in the soil or under litter and emerge at night to feed. They undergo complete metamorphosis, pupating in the soil.

Risks & Benefits

Potential risks: Cutworms are significant agricultural pests, capable of causing considerable damage to young plants, leading to crop loss. They can be particularly destructive in spring gardens. Benefits: As part of the food chain, they can be a food source for birds and other predators. However, their beneficial impact is generally outweighed by their pest status in cultivated areas.
