Asian gypsy moth

The Asian gypsy moth, Lymantria dispar asiatica, is a serious defoliating forest pest that can feed on several hundred different tree species. Females of this subspecies of the gypsy moth are capable of strong directed flight and are attracted to lights, which often results in egg masses being laid on either the superstructure of vessels or their cargo. Multiple introductions of the Asian gypsy moth strains have occurred when egg masses on ships from Japan and Far East Russian ports hatch after entering ports in western North America, and from pupae on military equipment or troop belongings entering the east from Germany.
