White line moth

Forests and Woodlands, Grasslands and Prairies, Agricultural and Cultivated Areas

The eggs of white line moth are typically found on the underside of leaves of the host plant. As larvae, white line moth often remain hidden during the day in the foliage or within folded leaves, emerging at night to feed. The caterpillar stage can be found in a variety of habitats where host plants grow, such as meadows, fields, and gardens. Pupae are generally located in the soil or leaf litter, where they remain until they emerge as adults. Adult white line moth are nocturnal and are usually encountered at night near sources of light or feeding on nectar from flowers in the same regions where larvae and pupae develop. To search for them, one would carefully inspect the host plants and surrounding soil, especially during night-time or early morning.

The suitable time to find adult white line moth is typically at night since most noctuid moths are nocturnal. For other life stages, the daytime may be appropriate when the caterpillars or pupae are active.

Mild, calm, and humid nights are typically ideal for finding adult white line moth, as they are less active in colder temperatures. For finding eggs or caterpillars, weather that is not excessively hot or dry would be suitable as these conditions can desiccate or harm these life stages.
