If You Ever Spot This Insect — Kill It Immediately: The Spotted Lanternfly Invasion Is Real
The Spotted Lanternfly (Lycorma delicatula) may look like a harmless, even beautiful insect with its dotted wings and vibrant colors, but don’t be fooled. This invasive pest is causing havoc across North America, and experts are urging the public: If you see one — kill it immediately. Here’s why this pest is so dangerous, and what steps you need to take if you encounter one.
Why the Spotted Lanternfly Is a Threat
Originally from Asia, the Spotted Lanternfly was first discovered in Pennsylvania in 2014. Since then, it has rapidly spread to multiple states and shows no signs of slowing down. The primary concern? It feeds on over 70 plant species, including:
- Grapevines
- Fruit trees (apple, peach, cherry)
- Maples
- Hops
- Hardwood trees
By feeding on the sap of these plants, the lanternfly weakens them and leaves behind a sugary excretion called honeydew. This sticky substance encourages the growth of sooty mold, a fungus that blocks sunlight and stunts plant growth. It’s not just an agricultural nightmare—it’s an environmental crisis.
How to Identify a Spotted Lanternfly
Recognizing this pest is key to controlling its spread. Here’s how to identify it in each stage of its life cycle:
1. Eggs (Fall to Spring)
- Appear as grayish mud-like smears on trees, vehicles, rocks, or outdoor furniture.
- Each egg mass contains 30–50 eggs and is about 1 inch long.
