What is a Lanternfly?
The lanternfly, despite its charming name, is a significant pest that originated in China and was first spotted in the United States in Pennsylvania in 2014. Since then, it has been spreading across various states, leaving a trail of agricultural and ecological damage. This invasive insect feeds on the sap of a wide range of plants and trees, weakening them and leading to the growth of a harmful sooty mold.
The Damage They Cause
Lanternflies are a threat not just to commercial farmers, but to backyard gardeners as well. Their feeding process not only weakens the plant but can also lead to the growth of sooty mold due to the sticky, sweet substance called honeydew that they excrete. This mold further harms the plant by inhibiting photosynthesis, effectively choking the life out of it. The impact of these insects can be devastating, as they target a variety of plants, including valuable crops and beloved ornamental trees.
Appearance of the Lanternfly
Identifying a lanternfly is key to controlling its spread. Adults are about an inch long and half an inch wide, with a striking appearance. Their wings are gray with black spots at the front, and a blend of red and black sections hidden beneath. When they fly, the bright red underwings create a vivid flash of color that is quite eye-catching. Juveniles, known as nymphs, are black with white spots and turn red before reaching maturity.
Feeding Process
The lanternfly uses a long, needle-like mouthpart to pierce the plant and access the sap. This feeding style is particularly harmful because it allows the insect to tap directly into the plant’s nutrient channels, sapping its life energy away efficiently. Observing them at work on plants is both fascinating and horrifying, as the insects methodically drain the life from their hosts.

First Sightings and Spread
Lanternflies were first detected in the U.S. in Pennsylvania, likely arriving on a shipment of stones or other goods from Asia. Since their initial detection, they have been moving across the states, primarily along the East Coast, but their range is expanding as they find suitable climates and host plants.
What to Do If You See a Lanternfly?
If you spot a lanternfly, it’s essential to take action. The recommended course of action is to eliminate the insect, as their significant potential for damage necessitates prompt control measures. You can squash the adults or nymphs directly, but one of the most effective ways to manage lanternfly populations is by destroying their egg masses before they hatch.

Destroying Lanternfly Eggs
The egg masses of the lanternfly look like smears of gray mud and are often found on smooth surfaces like the bark of trees, stones, or even outdoor furniture. If you find an egg mass, you can scrape it off into a bag containing alcohol or hand sanitizer, which kills the eggs. This proactive approach can help prevent the spread of these destructive pests.

Dealing with lanternflies has been an eye-opening experience, teaching me that sometimes, taking harsher measures against certain insects is necessary to protect the broader ecosystem. If you spot a lanternfly, remember the damage they can cause and take action. It’s a small step that can help save many trees and plants in your area—and possibly prevent the spread to new regions. As stewards of our environments, it’s our responsibility to manage this problem effectively and keep our landscapes healthy and thriving.
