Spotted lanternfly nymphs and adults cause damage when they feed, sucking sap from stems and leaves. Adults prefer to feed and lay eggs on the tree of heaven (Ailanthus altissima).  If allowed to spread in the United States, this pest could seriously harm the country’s grape, orchard, and logging industries.  We have reached out to researchers in Korea to learn more about this destructive pest, and PDA is conducting research on the ground to see if removing Ailanthus host trees, which also happen to be invasive, and chipping the wood effectively kills spotted lanternfly nymphs.

Host Plants

Apples, plums, cherries, peaches, nectarines, apricots, almonds, and pine. It also feeds on oak, willow, sycamore, walnut, poplar, and grapes. The insect will change hosts as it goes through its developmental stages.

 

Description

Adult spotted lanternflies are approximately 1 inch long and onehalf inch wide, and they have large and visually striking wings. Their forewings are light brown with black spots at the front and a speckled band at the rear. Their hind wings are scarlet with black spots at the front and white and black bars at the rear. Their abdomen is yellow with black bars. Nymphs in their early stages of development appear black with white spots and turn to a red phase before becoming adults. Egg masses are yellowish-brown in color, covered with a gray, waxy coating prior to hatching.

Damage

Both nymphs and adults of spotted lanternfly cause damage when they feed, sucking sap from stems and leaves. This can reduce photosynthesis, weaken the plant, and eventually contribute to the plant’s death. In addition, feeding can cause the plant to ooze or weep, Pest Alert Animal and Plant Health Inspection Service Plant Protection and Quarantine Spotted Lanternfly (Lycorma delicatula) resulting in a fermented odor, and the insects themselves excrete large amounts of fluid (honeydew). These fluids promote mold growth and attract other insects.
