Boxwood psyllids are small insects that produce a distinctive cupping of leaves as the immature stages (nymphs) remove sap from tender expanding foliage. They feed only on boxwood; the damage is especially noticeable on American boxwood. These insects affect the appearance of the plant but are not a threat to plant health or vigor.
