Fiorinia externa, the elongate hemlock scale was accidentally introduced into North America from Japan and is now established in most parts of the north-eastern U.S.[2] It has become a serious pest of hemlock (Tsuga) and some related conifers from the family Pinaceae. Dense colonies of the scale insect result in yellowing, shedding of leaves, dieback and occasional tree death.[3]
