statisena

Statisena is a genus of moths in the family Geometridae. These moths are characterized by their often cryptic coloration, which allows them to blend in with their surroundings, typically bark or foliage, providing camouflage from predators. The larvae of statisena, like other geometrids, are known as "inchworms" or "loopers" due to their unique method of locomotion, moving with a looping motion by alternately hooking their prolegs and thoracic legs. This characteristic movement is a result of having fewer pairs of prolegs than typical caterpillars.

The distribution of statisena is primarily within the Palearctic region. Species within this genus inhabit a variety of environments, including forests and woodlands, where their host plants are found. The life cycle of statisena follows the typical insect metamorphosis: egg, larva, pupa, and adult. Adults are generally nocturnal or crepuscular, feeding on nectar from flowers or remaining inactive during the day. Research on statisena species often focuses on their ecological roles, including their impact on plant life as herbivores and their contribution to biodiversity. The specific host plants can vary depending on the species, but often include trees and shrubs common to their native habitats.
