Here is some helpful information to pass along…
More info on the spotted lanternfly (SLF). The spotted lanternfly is an invasive insect that feeds on the sap of over 70 plants, including grapes, hops, and fruit trees, causing significant damage to crops and forests. It is characterized by its distinctive gray forewings with black spots and red and black hindwings. To control its spread, residents should inspect vehicles and outdoor items for egg masses (gray, clay-like) and destroy them, report sightings to local authorities, and stomp on adult insects.
Identification
Adults: About 1 inch long and 1/2 inch wide, with gray forewings marked with black spots and black-and-red hindwings.
Nymphs: Young stages are black with white spots and develop red patches as they grow.
Egg Masses: Gray, mud-like masses that turn brown and crack as they age.
Damage Caused
Sap Feeding:
SLF feeds on plant sap, weakening plants and potentially causing significant damage to agricultural crops and forests.
Honeydew and Sooty Mold:
The insects excrete a sticky substance called honeydew, which promotes the growth of black sooty mold on plants and surfaces.
How to Control and Prevent Spread
Inspect Vehicles:
Before leaving a quarantine zone, thoroughly check your vehicle, including the undercarriage, for SLF eggs or insects.
Destroy Egg Masses:
Scrape egg masses from surfaces and destroy them by smashing them and placing them in a bag with hand sanitizer or rubbing alcohol.
Stomp on Adults:
If you see an adult spotted lanternfly, stomp on it immediately.
Report Sightings:
Report any sightings of SLF, especially in areas where it is not yet established, to your local agricultural or environmental agency.
