🚨 They’re Here! What You Need to Know About the Spotted Lanternfly
If you suddenly notice clusters of strange insects covering a tree in your backyard, don’t ignore them.
The insects shown in the image appear to be spotted lanternflies (Lycorma delicatula), an invasive planthopper that has been spreading in parts of the United States. Adults are about 1 inch long, with light brown or pinkish wings covered in black spots.
🐛 Why Are Spotted Lanternflies a Problem?
Spotted lanternflies feed on the sap of many plants. Their preferred host is the tree-of-heaven, but they can also feed on grapevines, fruit trees, hops and various hardwoods.
As they feed, they produce a sticky sugary substance called honeydew. This residue can encourage the growth of sooty mold and attract other insects.
Large numbers can gather together on tree trunks, branches and other surfaces, which is why seeing dozens—or even hundreds—at once can be alarming.
🔎 How to Recognize Them
Adult spotted lanternflies typically have:
Light brown/tan wings with black spots
A pinkish or reddish appearance when viewed from certain angles
Black legs and head
A yellow abdomen with black markings
Red-and-black hind wings that become visible when the wings open
Adults are roughly 1 inch long and ½ inch wide.
Young nymphs look completely different. Early-stage nymphs are black with white spots, while later nymphs develop red coloring along with black and white markings.
⚠️ What Should You Do If You See One?
Don’t immediately assume every spotted insect is a lanternfly. Correct identification matters, because there are native insects that can look similar.
If you believe you’ve found a spotted lanternfly:
Take a clear photograph.
Note exactly where you found it.
Check nearby trees, outdoor furniture, vehicles and other objects for additional insects or egg masses.
Follow your local agriculture department’s reporting and disposal guidance.
Spotted lanternflies can hitchhike on vehicles and outdoor equipment, so checking items before moving them from an infested area is also important.
🥚 Don’t Forget the Eggs
Egg masses are especially important because they can survive the winter.
They are usually covered by a grayish, putty-like coating and can look like a smear of cracked mud. Each egg mass can contain around 30–50 eggs and may be found on trees, rocks, fences, vehicles, grills and other outdoor surfaces.
🌳 Why Early Detection Matters
The spotted lanternfly is considered an invasive pest because it can affect agriculture and plants across its range. Early detection and preventing the insect from spreading to new areas are important parts of controlling the population.
So if you spot one in your yard, don’t simply walk past it. Take a picture, identify it carefully and check your surroundings.
