What Is the Spotted Lanternfly?
The spotted lanternfly is a planthopper native to parts of China, India, and Vietnam, but it was first discovered in the United States in Pennsylvania in 2014. Since then, it has spread to numerous other states, including New Jersey, Virginia, and Ohio.
Adult lanternflies are about 1 inch long and half an inch wide, with distinctive markings. The forewings are gray with black spots, while the hindwings feature a striking red and black pattern with a white band. Nymphs, or juvenile lanternflies, start out black with white spots, transitioning to red before becoming adults.
These insects primarily feed on the sap of over 70 different plant species, including important crops like grapes, apples, and maple trees. This feeding behavior makes them a significant threat to U.S. agriculture, particularly the grape-growing (viticulture) industry.
Why Is It Important to Kill the Spotted Lanternfly?
The presence of the spotted lanternfly is problematic for several reasons:
- Economic Damage: The lanternfly’s feeding stresses plants, making them more susceptible to disease. For commercial growers, this can lead to significant crop yield losses, particularly in vineyards where grapevines are a primary target. Affected plants may also have lower resistance to environmental stresses, affecting the long-term health of agricultural fields.
- Environmental Impact: Beyond agriculture, the lanternfly feeds on and damages native trees, disrupting local ecosystems. The infestation can weaken tree health and make them more vulnerable to other pests or diseases, leading to a decline in biodiversity.
- Nuisance in Residential Areas: The lanternfly excretes a sticky substance known as honeydew as it feeds, which can cover nearby surfaces like patios, decks, and cars. This sticky residue attracts bees and wasps and can lead to the growth of sooty mold, which further damages plants. Additionally, the honeydew can make outdoor living spaces unpleasant for homeowners.
