Range

There may be some populations east of Rocky Mountains in eastern United States and southern Canada.(1)
"spotty distribution along the Atlantic coast from Connecticut to Georgia and west to northern Kentucky." BAMONA

Habitat

Found in open areas, near and in cities.(1)

Food

Many trees and shrubs, including ailanthus (tree of heaven, paradise tree), birch, ash, elm, alder, wild cherry, maple, lilac, willow, and apple.(1)

Remarks

It is a silk producing moth. It was introduced from China in the late 1800s.
There is legitimate debate as to whether there are still wild populations of this species in our area. The images here so far are from captive, hand-raised populations.
