In recent years, an invasive pest has made headlines and caused widespread concern in several US states. The spotted lanternfly (Lycorma delicatula) is a conspicuous but destructive insect notorious for the significant damage it causes to agriculture and the environment.
Here’s everything you need to know about the spotted lanternfly, why controlling its population is so important, and how you can safely contribute to its control.
What is the spotted lanternfly?
The spotted lanternfly is an invasive cicada species originally from parts of China, India, and Vietnam. It was first detected in Pennsylvania in the United States in 2014. Since then, it has spread to numerous other states, including New Jersey, Virginia, and Ohio.
This pest feeds primarily on the sap of over 70 different plant species, including grapevines, apple trees, pines, and maples, and thus poses a significant threat to U.S. agriculture and forestry.
Adult lanternflies are about 2.5 cm long and 1.25 cm wide and have distinctive wings. Their forewings are gray with black spots, while their hindwings have contrasting red and black spots with a white band. In the larval stage, they are black with white spots and turn red before reaching adulthood.

Economic damage: This insect poses a serious threat to viticulture, among other crops. The feeding activity of the lanternflies stresses the plants, making them susceptible to disease and potentially leading to significant crop losses.
Environmental impact: In addition to agriculture, lanternflies can damage or kill native trees, disrupting local ecosystems.
Nuisance in residential areas: While feeding, lanternflies excrete a sticky substance called honeydew, which attracts bees and wasps and can lead to the formation of sooty mold. This mold can damage the plants it covers and leave patios, decks, and cars sticky and black.
