The spotted lanternfly: a new invasive pest to know about
Lycorma delicatula, commonly referred to as the spotted lanternfly, is an invasive insect that’s native to China. It was first seen in Pennsylvania in September 2014, but has since spread to other regions of the country. Much like the gypsy moth, which is present in several states, the spotted lanternfly is capable of destroying several important crops. Take a closer look at the threat this insect presents, and learn how to prevent spreading them to new areas when you move.
- The spotted lanternfly feeds on trees, which puts fruit crops and the logging industry at risk
- Each female can lay 60-150 eggs every fall
- They’ve been seen in Pennsylvania, Delaware, New York and Virginia
- There are currently no known natural enemies making an impact on the population
Identifying, reporting and removing the spotted lanternfly
Spotted lanternflies will look different depending on the time of year. Adults will be seen in autumn months, while the nymphs will be present in spring and summer. Eggs are believed to hatch in early May.
Adults are approximately one-inch long and a half-inch wide. They’re easily identified by the black spots on their wings, which are gray when the insect is at rest. They also have hind wings with a black and red pattern.
Nymphs are either black with white spots or black with white spots and red patches, depending on the stage of development.
Eggs will be found in masses, with a dark mud-like consistency in the early stages. Later stages will have four to seven columns of one-inch long eggs.
Signs of infestation
- Egg masses on trees, buildings, vehicles or other smooth surfaces
- Trees or plants that weep and have a fermented smell
- A buildup of sticky fluid (called honeydew)
- Mold on leaf surfaces
What to do if you find the spotted lanternfly
If you see any life stage of the spotted lanternfly, you should take immediate action. In areas where the spotted lanternfly has already been reported, you should destroy it. Egg masses can be scraped from the surface they’re attached to, double-bagged and thrown away. Adults and nymphs can be crushed or swatted, but that may not be a feasible option since they’re able to jump long distances. Large infestations might be better controlled with professional pest control services. Any destroyed egg masses should be reported here.
If you find any in a region where they haven’t been previously seen, you should attempt to capture one and preserve it in alcohol or take a photo. You should also call the invasive species hotline at 1-866-253-7189 to report it.
What is the U.S. Department of Agriculture doing?
In February 2018, the U.S. Department of Agriculture (USDA) announced a $17.5 million investment to stop the spread of the invasive pest. This commitment came after the insect was spotted in more areas of Pennsylvania and in neighboring New York, Delaware and Virginia. According to the USDA, this emergency funding will be used to educate the public and support the goal of containing the infestation.
What do I do if I’m moving from a quarantined area?
If you’re moving from an area within the spotted lanternfly quarantine, you should take precautions to avoid spreading them to other areas of the United States. The Pennsylvania Department of Agriculture has created a checklist for residents to use before moving. They suggest checking all vehicles and outdoor items for egg masses, adults and nymphs. Items to inspect include:
- Camping gear
- Building materials
- Yard and garden tools
- Outdoor furniture
If any are found, follow the instructions above for removing and disposing of them.
