noctuid moths

A large family of mostly nocturnal moths (family Noctuidae) that includes thousands of species worldwide. Noctuids are typically dull-colored and active at night. Their larvae—commonly known as cutworms or armyworms—are important herbivores in native ecosystems.

In California, many noctuid species rely on native grasses, sedges, and herbaceous plants as hosts for their larvae. Adult moths may also visit flowers at night to feed on nectar, making them critical nocturnal pollinators.

Noctuid moths play a crucial role in the food web, serving as prey for bats, birds, amphibians, and insectivorous mammals. Supporting native plant diversity helps maintain healthy populations of noctuid insects.
