Invasive spotted lanternfly found in Illinois

SPRINGFILED, Ill. (KBSI) – The Illinois Department of Agriculture has confirmed the first detection of spotted lanternfly (SLF) after a report on September 16, 2023. On September 18, specimens were collected and submitted for identification and were confirmed on September 26. The spotted lantern does not pose any risk or health concerns, according to the Illinois Department of Agriculture.

SLF is an invasive plant hopper from eastern Asia. The bug was first found in America in southeastern Pennsylvania, spread throughout the east and recently the Midwest. There have been confirmed identifications in Indiana, Michigan, Ohio and southern and eastern states.

SLF feeds off of  grapes, tree of heaven and maple trees, according to the Illinois Department of Agriculture. When feeding, the bug produces honeydew, a sticky liquid, which accumulates on foliage and other parts of plants.

SLF is believed to move easily on wood surfaces, vehicles, outdoor articles and more. Prevention and early detection are vital to limiting its ability to move and intrude upon new areas, according to Illinois Department of Agriculture. Persons are encouraged to send photos of potential sightings to  lanternfly@illinois.edu.

Communities are continuing to learn about SLF and work on how to minimize the spread and impact on industry and natural resources.

The Illinois Department of Agriculture says to do the following to help:

• Report sightings – If you see SLF or suspect it, report it to lanternfly@illinois.edu. A fact sheet, including photos, is available through the University of Illinois Extension.
• Remove and destroy pests – crush nymphs and adults, scrape egg masses into a container with hand sanitizer or rubbing alcohol to kill them. Remember to take photos first, and report this!
• Check your vehicles, boat, camper, outdoor articles, etc. – Before leaving an area, do a quick inspection for any life stages. Destroy any eggs or insects found.
• Keep your eyes open and spread the word (not the pest) – IDNR needs the public’s help to look for and report this pest, and to also strengthen the outreach about it. It will likely impact everyone in Illinois one way or another, so the more awareness, the better.
