Eacles imperialis, known as the Imperial Moth, is a large, striking moth found in deciduous forests across North America. It features vibrant yellow and purple markings, with a wingspan up to 6 inches. Active primarily at night, its caterpillars feed on oak and maple leaves, playing a crucial role in the forest ecosystem.

Eacles imperialis, commonly known as the Imperial Moth, is native to North America. Its geographical distribution includes parts of the United States, primarily in the eastern and southeastern regions, extending into parts of Canada and Mexico. It is commonly found from Nova Scotia and Quebec in the north, through the eastern United States, to Texas and Florida in the south, and into the Gulf Coast and parts of Central America.

The Imperial Moth typically inhabits deciduous forests, woodlands, and suburban areas where its larval host plants are abundant. These environments generally have moderate to warm climates, with sufficient humidity. The moths are often found in areas with a variety of hardwood trees, which provide suitable conditions for both larval development and adult activity.

Eacles imperialis larvae are polyphagous, feeding on a wide range of deciduous trees such as oak, maple, and sweetgum. This adaptability allows it to thrive in diverse forested environments. The adults, however, do not feed and are primarily nocturnal, engaging in activities like mating and laying eggs at night. The Imperial Moth plays a role in the ecosystem as both a pollinator and as part of the food web, serving as prey for birds, bats, and other insectivores.
