If you’ve recently noticed a colorful, spotted insect on your property, you might be looking at the invasive Spotted Lanternfly (Lycorma delicatula). While it may look harmless or even beautiful with its distinctive gray wings dotted with black and splashes of red and yellow, this pest is far from innocent. The Spotted Lanternfly is a serious threat to agriculture, forests, and even your backyard plants. Here’s why it’s crucial to act quickly and follow specific steps if you spot this insect.
What is a Spotted Lanternfly?
The Spotted Lanternfly is an invasive species native to Asia, particularly China, India, and Vietnam. It was first detected in the United States in 2014 in Pennsylvania and has since spread to multiple states, causing significant damage to crops, trees, and various plant species. This pest feeds on the sap of plants, weakening them and making them susceptible to disease and other pests.
The Spotted Lanternfly has a distinct appearance, making it relatively easy to identify:
Wings: Grayish with black spots; when wings are open, you can see the bright red hindwings.
Body: The body is black with white spots, and the legs and head are black.
Size: It can grow up to 1 inch long and 1/2 inch wide.
Why You Should Kill It Immediately
The Spotted Lanternfly poses a serious risk to a wide range of plants, including fruit trees (like apples and peaches), grapevines, hops, and hardwood trees. It feeds by sucking sap from the stems and leaves, which can lead to wilting, dieback, and even the death of the plant. Furthermore, it excretes a sugary substance known as honeydew, which promotes the growth of sooty mold—a black, unsightly fungus that can cover plants and inhibit photosynthesis.
This pest’s ability to reproduce rapidly makes it even more dangerous. Each female Spotted Lanternfly can lay up to 50 eggs in a single mass, which she can hide in crevices of trees, rocks, outdoor furniture, and even vehicles, aiding its spread.
Steps to Take if You Spot a Spotted Lanternfly:
1. Kill It on Sight
If you see a Spotted Lanternfly, kill it immediately. Squash it, capture it in a container, or use a pesticide if necessary. It’s crucial not to hesitate, as even one insect can lead to an infestation.
2. Report the Sighting
Report your sighting to your local agriculture department or extension office. In many states, there are hotlines or websites where you can log the location of your sighting. This helps authorities track the spread of the pest and implement control measures.
3. Inspect and Destroy Egg Masses
During the fall, females lay eggs in clusters that resemble a grayish, putty-like substance. These can be found on tree bark, outdoor furniture, vehicles, and other surfaces. If you spot an egg mass, scrape it off into a bag containing rubbing alcohol or hand sanitizer to kill the eggs. Dispose of the bag in the trash.
4. Remove Preferred Hosts
The Spotted Lanternfly is particularly attracted to the Tree of Heaven (Ailanthus altissima), an invasive species itself. If you have this tree on your property, consider removing it to reduce the likelihood of a Spotted Lanternfly infestation. Other host plants include grapevines, maples, and walnuts, which should be monitored closely.
5. Apply Sticky Bands and Traps
You can use sticky bands or traps on trees to catch Spotted Lanternflies as they climb up and down the trunks. Be sure to check these regularly and dispose of any captured insects.
6. Use Approved Insecticides
If the infestation is severe, you may need to apply insecticides. There are specific products approved for use against Spotted Lanternflies. Consult with a local expert or extension office for recommendations on safe and effective products.
Conclusion
The Spotted Lanternfly is more than just a nuisance; it’s a destructive force that can have significant economic and ecological impacts. By staying vigilant and taking immediate action if you spot one, you can help protect your local environment from this invasive pest. Remember, every Spotted Lanternfly you kill is one less threat to our crops, trees, and plants
