Lymantria dispar
Scientists say the North American and European Lymantria dispar moths are the same subspecies, Lymantria dispar dispar. But not all scienitsts agree. The U.S. Department of Agriculture says the Asian subspecies is any kind of L. dispar in which the female adult can fly despite L. d. asiatica not being the only accepted subspecies that is capable of flight. Traditionally, L. dispar has been referred to as "gypsy moth" even when referring to Japanese, Indian and Asiatic spongy moth populations.
