"Lymantria dispar japonica" was originally described as a variation of "Lymantria dispar" by Victor Motschulsky in 1860. It was treated as a full species by Kirby in 1892 and Swinhoe in 1903. Strand in 1911 and again in 1923 treated "L. d. japonica" as a subspecies of "L. dispar", since then other authors (Inoue 1957, Schintlmeister 2004) have also recognized the form from Japan as "L. d. japonica".
