What type of moths do you think was more common in the 19th century and why?

In the 19th century, species like the Luna moth and the Promethea moth were likely more common due to their natural habitats and the less industrialized environment of the time. The absence of extensive urbanization and pollution allowed for diverse ecosystems that supported various moth species. Additionally, many moths were less impacted by light pollution and habitat destruction, which have become significant threats in modern times. Overall, the 19th century's more balanced ecological conditions favored the prevalence of these beautiful moths.
