Sematuridae

Sematuridae is a family of moths in the superfamily Geometroidea. The family was first described by Frederic Moore in 1867. Moths in this family are primarily found in the Neotropical and Afrotropical regions. They are characterized by their generally medium to large size, with wingspans typically ranging from 2 to 4 centimeters. The coloration of Sematuridae moths can vary, but many species exhibit cryptic patterns that aid in camouflage, often mimicking bark or dead leaves. Some species also display warning coloration, suggesting they are unpalatable to predators.

The larvae of Sematuridae moths are generally smooth-bodied and feed on a variety of plants, with specific host plant preferences varying by species. Adults are typically nocturnal or crepuscular, meaning they are active at dawn and dusk. Their flight patterns are often described as strong and direct. While not extensively studied compared to some other moth families, research on Sematuridae contributes to our understanding of insect biodiversity and evolutionary relationships within the Lepidoptera order. The family contains several genera, and ongoing taxonomic research continues to refine the classification and relationships within Sematuridae.
