If you spot a spotted lanternfly (Lycorma delicatula), take immediate action to eliminate it. This invasive insect, native to China, has been a significant threat to agriculture and ecosystems in the U.S. since its first appearance in Pennsylvania in 2014. Lanternflies feed on sap from over 70 plant species, including crops like grapes, apples, and hops, weakening plants and making them vulnerable to disease. Their feeding also promotes the growth of sooty mold, which blocks sunlight and further damages plants.
Spotted lanternflies are about one inch long, with gray wings featuring black spots and red underwings. The nymphs are initially black with white spots and later turn red with white patches before becoming adults. They reproduce quickly and lay eggs on various surfaces, including trees, rocks, and vehicles, making it easy for the infestation to spread.
To control lanternflies, take the following steps:
- Eliminate Adults and Nymphs: Squash any spotted lanternflies you see to reduce the population.
- Destroy Egg Masses: Scrape off egg masses from surfaces and place them in a sealed bag with rubbing alcohol to kill the eggs.
- Report Sightings: Notify local authorities if you spot lanternflies in new areas.
- Inspect Outdoor Items: Check vehicles and outdoor equipment for egg masses or lanternflies before moving them.
- Use Traps and Insecticides: In severe infestations, use sticky traps or insecticides, following guidelines to protect beneficial insects.
By taking action, you can help prevent the spread of this destructive pest and protect agriculture and ecosystems.
