Lymantria dispar
The North American and European "Lymantria dispar" moths are considered to be the same subspecies, usually referred to as "Lymantria dispar dispar". Confusion over the classification of species and subspecies still remains. The U. S. Department of Agriculture defines the Asian subspecies as "any biotype of "L. dispar" possessing female flight capability", 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 gypsy moth populations.
