Sisena

Sisena is a genus of moths belonging to the family Geometridae. These moths are characterized by their often cryptic coloration, which helps them blend into their surroundings, typically bark or foliage. The wingspan of Sisena species can vary, but many are relatively small to medium-sized for the family. The larvae of these moths are commonly known as inchworms due to their characteristic looping locomotion. They are herbivorous, feeding on the leaves of various plants. The specific host plants can differ depending on the species and geographic location. Sisena moths are found in a range of habitats, often in forested areas or regions with sufficient vegetation to support their larval stages. The distribution of the genus is primarily within the Palearctic and Oriental realms. Like most moths, Sisena adults are typically nocturnal or crepuscular, becoming active during the evening and night. Their life cycle involves complete metamorphosis, with eggs hatching into larvae, which then pupate before emerging as adult moths. Identification of individual Sisena species can sometimes be challenging and may require examination of subtle morphological differences, particularly in the wing venation and genitalia. Research into the genus continues to explore its biodiversity, ecological roles, and evolutionary relationships within the Geometridae family.
