Spotted Lantern Fly

Spotted Lantern Fly


The spotted lanternfly ​(Lycorma delicatula) is an invasive plant hopper, primarily known to affect tree of heaven (Ailanthus altissima). It has been detected on many host plants, including apples, plums, cherries, peaches, nectarines, apricots, almonds, and pine. It also feeds on oak, walnut, poplar, and grapes. The insect will change hosts as it goes through its developmental stages. Nymphs feed on a wide range of plant species, while adults prefer to feed and lay eggs on tree of heaven (A. altissima). If allowed to spread in the United States, this pest could seriously harm the country’s grape, orchard, and logging industries. 


The spotted lanternfly is an invasive, sapsucking pest with forewings which are light brown transitioning from black spots at the front to a speckled band near the rear, while hindwings are scarlet with black spots.

Current Situation

The spotted lanternfly is present in China, India, Japan, South Korea, and Vietnam. The insect was detected in Pennsylvania in September 2014. This was the first detection of spotted lanternfly in the United States. Spotted lanternflies are invasive and can spread rapidly when introduced to new areas. While the insect can walk, jump, or fly short distances, its long-distance spread is facilitated by people who move infested material or items containing egg masses.
