Keep Spotted Lanternfly Out of California
The spotted lanternfly has now made its way into 13 eastern states. Be sure you are up to speed on this
invasive pest and view the resources provided by the California Department of Food and Agriculture.
The spotted lanternfly (Lycorma delicatula) (SLF) is an invasive pest, primarily known to feed on tree of
heaven (Ailanthus altissima) but has many other host plants, including grape, hop, apple, stone fruit,
maple, poplar, walnut, and willow. If allowed to spread in the United States, it could impact the country's
fruit, ornamental, and forest industries. Early detection is critical to prevent economic and ecological losses.
The public will play a key role in detecting spotted lanternfly and the success of stopping its spread
depends on help from the public to look for and report signs of the pest.
Origin: The spotted lanternfly is an invasive plant hopper that is native to China and likely arrived in North
America hidden on goods imported from Asia.
Current Distribution in the United States: The SLF was first detected in Pennsylvania in 2014 and
spread in the mid-Atlantic, infesting six states and found in 11. Five states have enacted quarantines and
inspections to slow artificial movement of the pest.
How it Spreads: 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. The spotted
lanternfly lays eggs on almost any surface, including vehicles, trailers,
outdoor equipment, and patio furniture.
Damage: Both nymphs and adults of spotted lanternfly cause
damage when they feed, sucking sap from stems and branches.
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, resulting in a fermented odor, and
the insects themselves excrete large amounts of fluid (honeydew).
These fluids promote mold growth and attract other insects.
