Didena

Didena is a genus of moths in the family Geometridae. These moths are found in various parts of the world, with species recorded in Europe, Asia, and North America. The exact distribution varies depending on the specific species within the genus. Didena moths are generally characterized by their moderately sized wings and typical moth morphology.

The larvae of Didena moths, like other geometrids, are commonly known as inchworms or loopers. They exhibit a unique method of locomotion, appearing to measure the ground by arching their bodies into a loop and then extending forward. The host plants for Didena larvae are diverse and can include various trees and shrubs, though specific preferences are tied to individual species.

Adult Didena moths are typically nocturnal or crepuscular, meaning they are active during the night or at dawn and dusk. Their diet usually consists of nectar from flowers. The appearance of adult moths can vary, with wing patterns and colors providing camouflage against their natural surroundings. Identification of specific species often relies on detailed examination of wing venation and genitalia. Research on Didena moths contributes to our understanding of insect biodiversity and ecological relationships within their habitats.
