Life Cycle of Autographa corusca
Egg After hatching from the egg, the larva of autographa corusca emerges, small and primarily focused on feeding. The coloration is typically muted, providing camouflage.
Larva At this phase, autographa corusca experiences rapid growth. Through multiple molts, it increases in size, and the color may vary as it develops. Its main function remains feeding.
Pupal During this resting stage, autographa corusca is encased in a chrysalis. Transformation occurs internally as the body structure reorganizes. Color and shape are obscured.
Adult Emerging from the pupa, the adult autographa corusca’s development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

How Can You Attract Autographa corusca
Most likely adults feed on nectar. Therefore, nectar-producing flowers can be used as a trap food to attract them, or a sugar bait can be applied to trees where they might land.
Rectangle
Habitat Preferences of Autographa corusca Through Different Life Stages
During the larval stage, autographa corusca can often be discovered on host plants where they feed and grow, generally in gardens, meadows, or agricultural fields with abundant vegetation. Searching for their pupae would typically involve examining the underside of the leaves of the host plants, or within the topsoil or litter near these plants. Adult autographa corusca are primarily active at night and attracted to light, so they are best sought after dusk using light traps or in areas with plenty of flowering plants they may visit for nectar.

When is the Best Time to Observe Autographa corusca
Nocturnal in nature, the suitable time to find adult autographa corusca would be at night. Larvae may be more active during the day and thus can be sought after then.
Rectangle
What is the Best Weather to Observe Autographa corusca
Ideal weather to find autographa corusca would include warm, humid nights for adult specimens, as these conditions are favorable for their flight activities. Dry and sunny conditions are more suitable for locating caterpillars during the day.

Hurt Plant

The autographa corusca causes harm primarily through feeding on the leaves of its host plants. As a result of their chewing of plant tissues, the foliage often shows clear signs of distress. These insects typically create irregular holes or notches in the leaves, which can sometimes lead to reduced photosynthesis efficiency and stunted growth in the affected plants.
