Nun moth larva

The nun moth, Lymantria monacha, an Eurasian pest of both broad leaf trees and conifers (spruce, fir, larch and pine) is closely related to the gypsy moth in appearance and behavior. Although the nun moth is not known to be established in North America, it poses an ever-present threat of being accidentally introduced because of its biology and behavior.

Since 1996, Forest Service scientists at the Northern Research Station have been studying the nun moth in quarantine to develop tactics to prevent its introduction and establishment in North America.
