The spotted lanternfly (Lycorma delicatula) is an invasive insect that should be eliminated immediately upon discovery. Native to China, it was first identified in Pennsylvania, USA, in 2014.
Since its arrival, the lanternfly has spread rapidly, inflicting considerable damage to agricultural crops and natural ecosystems. These pests feed on the sap of numerous plants and trees, weakening them and causing the secretion of a sticky substance called honeydew. This honeydew promotes the growth of sooty mold, which further damages plants by hindering photosynthesis.
Identifying lanternflies is fairly easy. Adult insects are about an inch long, with gray wings speckled with black spots and red and black markings on their undersides. The nymphs, or juvenile lanternflies, start off black with white spots and turn red as they mature. These insects have a needle-like mouthpart that pierces plants to suck out their sap, robbing them of essential nutrients.
If you come across a lanternfly, take immediate steps to eradicate it. Crush both adults and nymphs on sight. It’s also important to remove their egg masses, which resemble gray, mud-like patches. These should be scraped off and placed in a bag filled with alcohol or hand sanitizer to ensure the eggs are destroyed.
Tackling the lanternfly problem is crucial for protecting our plants and the environment. If you spot one, act quickly to prevent further damage and help preserve the health of our ecosystems.
