Overview

Lycorma delicatula, or Spotted Lanternfly (SLF), is an invasive plant hopper from Asia. In the United States, it was first found in Pennsylvania in 2014. It is not yet established in New York State. SLF threatens the agriculture and forestry industries, and is also a nuisance pest. The nymphs and adults feed on over 70 different plants with piercing sucking mouthparts. 

Agricultural Impact

SLF has the potential to damage multiple agricultural crops in New York. SLF is a pest of apples, grapes, hops, maple, walnut, and others. New York is estimated to produce more than 30 million bushels of apples each year, while grapes in New York are valued at an annual harvest of $52.8 million. Additionally, the expanding hops industry and the maple and timber industries would also be negatively impacted by the spread of SLF.

Our Work

Since January 2018, the Department has been working cooperatively with multiple state and federal partners to monitor for SLF populations in New York.  Regulatory actions have also been put in place to mitigate the risk of SLF arriving in New York. Outreach to the public, trade groups, and other stakeholders is ongoing to provide up-to-date information related to SLF. No viable SLF populations have been identified in New York at this time.

Quarantine

On October 2, 2018, the Department enacted an external quarantine covering the areas of states where SLF is known to have populations. The quarantine restricts the movement of goods and vehicles that could transport SLF to New York State from certain counties in Delaware, Maryland, New Jersey, Pennsylvania, and Virginia.

Take Action

The public can help the Department by reporting SLF immediately after it is found. Follow these steps:

  • Take a photo
  • Collect a sample and place it in a freezer or in a jar with rubbing alcohol or hand sanitizer. 
  • Contact the SLF responders
