Cerastis

Cerastis is a genus of moths belonging to the family Noctuidae, commonly known as owlet moths or dart moths. These moths are found primarily in North America and Eurasia.

Cerastis moths are typically characterized by their medium size and relatively drab coloration, often featuring shades of brown, grey, or black. The forewings usually exhibit intricate patterns and markings, which aid in camouflage. The hindwings are generally lighter in color than the forewings and may lack distinct markings.

The larvae, or caterpillars, of Cerastis species are typically nocturnal feeders, consuming the foliage of various herbaceous plants and trees. Some species can be considered minor agricultural pests.

Identification of specific Cerastis species can be challenging, often requiring examination of the genitalia under magnification. Several species are closely related, leading to taxonomic complexities.

The life cycle of Cerastis moths follows the typical pattern for Noctuidae: egg, larva, pupa, and adult. The number of generations per year varies depending on the species and the geographic location.
