- Gray or tan forewings
- Distinctive black spots
- Bright red hindwings
- Black-and-white markings on their body
- A roughly 1-inch body length
The red underwings are particularly noticeable when the insect flies or opens its wings.
Spotted Lanternfly Nymphs
Young spotted lanternflies look very different from adults.
Early nymphs are black with white spots. As they mature, they develop red coloration along with the black-and-white markings.
This means you may encounter a spotted lanternfly before it ever develops the familiar red-winged adult appearance.
Where Do Spotted Lanternflies Live?
Spotted lanternflies can be found in a variety of environments, including gardens, yards, forests, orchards, vineyards, and other areas containing suitable host plants.
One plant deserves particular attention: tree-of-heaven (Ailanthus altissima).
Tree-of-heaven is an invasive tree that can serve as an important host for spotted lanternflies. However, lanternflies can feed on many other plants as well.
Why Gardeners Should Pay Attention
A small number of lanternflies may not cause noticeable damage to a mature plant.
The concern increases when populations become abundant.
Large infestations can mean hundreds or even thousands of insects feeding in the same area. This concentrated feeding can stress plants and create substantial amounts of honeydew.
If you grow grapes, fruit trees, ornamental plants, or other valuable vegetation, keeping an eye out for unusual insect activity is especially worthwhile.
What Should You Do If You Find One?
First, identify it carefully.
Many insects have spots, unusual wings, or bright colors, and not every spotted insect is a spotted lanternfly.
If you're confident you've found one, follow the recommendations of your local agriculture or environmental authorities.
Depending on where you live, you may be encouraged to report the sighting.
If You Only See One
If the insect is confirmed to be a spotted lanternfly and local guidance recommends removing individual insects, physically eliminating it may be appropriate.
However, don't automatically spray an entire garden with insecticide.
Broad pesticide use can harm beneficial insects and other wildlife and isn't always necessary for an isolated sighting.
If You See Many
A large concentration deserves more attention.
Look around nearby trees, plants, fences, and other surfaces for additional insects or egg masses.
If your area has an established reporting system, contact the appropriate local or state agricultural authority and follow its current instructions.
Don't Forget About the Egg Masses
One of the biggest reasons spotted lanternflies can spread is their ability to lay eggs on a surprisingly wide variety of surfaces.
Egg masses can appear on:
- Tree trunks
- Branches
- Rocks
- Outdoor furniture
- Vehicles
- Landscaping materials
- Fences
- Other smooth outdoor surfaces
Fresh egg masses may look like rows of small eggs covered with a grayish protective coating.
Older egg masses can become harder to recognize as the covering weathers and cracks.
Why Egg Masses Matter
Adult insects are mobile, but egg masses can be accidentally transported from one location to another.
That's why checking outdoor items before moving them can be an important part of preventing the insect from spreading.
This is particularly important when traveling from an area where spotted lanternflies are established to another location.
How to Help Prevent the Spread
You don't need to be an entomologist to help.
A few simple habits can make a difference.
Check Your Vehicle
Before leaving an area where spotted lanternflies are common, inspect your vehicle.
Pay attention to:
- Wheel wells
- Bumpers
- Truck beds
- Trailers
- Outdoor equipment
Look for both insects and egg masses.
Inspect Outdoor Items
If you're moving firewood, camping equipment, furniture, plants, landscaping materials, or other outdoor belongings, inspect them carefully.
Egg masses can be surprisingly easy to overlook.
Learn the Local Rules
Management recommendations can vary by location because spotted lanternfly populations and regulations aren't identical everywhere.
When in doubt, check your state or local agriculture department for the most current instructions.
Natural Predators and the Garden Ecosystem
Spotted lanternflies are not completely without predators.
Birds, spiders, praying mantises, and other insects may feed on them. However, natural predators aren't considered a simple solution for controlling established populations.
That's another reason to avoid turning your entire garden into a chemical battlefield after seeing one insect.
A thoughtful, targeted approach is generally better for the wider garden ecosystem.
Should You Spray Spotted Lanternflies?
Not necessarily.
The right response depends on the number of insects, the plants involved, your location, and local recommendations.
Using an insecticide without identifying the insect or understanding the infestation can do more harm than good.
You could kill pollinators and beneficial insects while failing to address the underlying source of the infestation.
If treatment is recommended, use products exactly according to their labels and follow local guidance.
Tips for Gardeners
Inspect Plants Regularly
Take a few minutes each week to look at your trees and plants.
Pay particular attention to unusual clusters of insects, sticky leaves, or black sooty growth.
Learn the Different Life Stages
Knowing what nymphs, adults, and egg masses look like makes spotting an infestation much easier.
Pay Attention to Trees
Look closely at tree trunks and branches, especially around plants known to attract lanternflies.
Don't Transport the Problem
Before moving outdoor items, check them for insects and egg masses.
This simple step is particularly important when traveling.
Frequently Asked Questions
Are spotted lanternflies dangerous to people?
No. Spotted lanternflies are not generally considered a danger to people. They are a plant pest, not an insect that typically bites or stings humans.
Do spotted lanternflies bite?
They are not known for biting people. Their mouthparts are designed for feeding on plant fluids.
Can spotted lanternflies kill trees?
A single lanternfly is unlikely to kill a healthy mature tree. However, heavy infestations can place considerable stress on plants, particularly when combined with other environmental stresses.
Why are spotted lanternflies attracted to my yard?
They may be attracted by suitable host plants and trees in or around your property. Tree-of-heaven is an important host, but spotted lanternflies can feed on many other plants.
What do spotted lanternfly eggs look like?
Egg masses can resemble rows of small eggs covered with a grayish, mud-like or waxy coating. As they age, the covering may become cracked and weathered.
Should I report a spotted lanternfly?
That depends on where you live. Some jurisdictions have specific reporting programs or management requirements. Check with your local or state agricultural authority for current guidance.
Can I get rid of spotted lanternflies naturally?
For an isolated insect, physical removal may be sufficient where local guidance recommends it. Larger infestations can be more complicated and may require an integrated approach.
Do spotted lanternflies only attack fruit trees?
No. They feed on a wide range of plants and trees. Grapevines, hardwoods, fruit trees, and ornamental plants can all be affected.
Final Thoughts
The spotted lanternfly is certainly an eye-catching insect. Those black spots and flashes of brilliant red make it almost impossible to ignore.
But when you're gardening, pretty doesn't always mean harmless.
If you spot one, don't panic. Take a moment to make sure you've identified it correctly, look for additional insects or egg masses, and check the recommendations for your area.
And remember: sometimes the most helpful thing a gardener can do isn't reaching for a bottle of pesticide—it's simply paying attention, identifying the pest, and knowing what to do next.
