Spotted lantern flies have been rapidly spreading across the United States, raising concerns about their impact on agriculture and the environment. While they may not pose a direct threat to humans, their ability to damage plants and disrupt ecosystems makes them a pest to be reckoned with. At flyermedia.net, we provide comprehensive information on spotted lantern flies, including their potential dangers, how to identify them, and effective strategies for controlling their spread.
1. What are Spotted Lantern Flies?
Spotted lantern flies (Lycorma delicatula) are invasive planthoppers native to Asia. They were first discovered in the United States in Pennsylvania in 2014 and have since spread to numerous other states.
1.1 Identification
- Nymphs: Young spotted lantern flies go through several stages called instars. Early instars are black with white spots, while later instars develop red patches.
- Adults: Adult spotted lantern flies are approximately 1 inch long and have distinctive wings. Their forewings are gray with black spots, and their hindwings are red with black spots and a white band.

1.2 Life Cycle
Spotted lantern flies have a one-year life cycle:
- Eggs: They lay eggs in masses covered with a mud-like substance on trees, rocks, and other surfaces.
- Nymphs: Nymphs hatch in the spring and go through four instars.
- Adults: Adults emerge in the summer and are active until winter, when they lay eggs.
2. Are Spotted Lantern Flies Dangerous to Humans and Pets?
Spotted lantern flies do not bite or sting and are not known to transmit diseases to humans or animals. However, they can be a nuisance due to their sheer numbers and the sticky honeydew they produce.
2.1 Direct Threats to Humans
- No Biting or Stinging: Spotted lantern flies lack the physical capability to bite or sting humans. Their mouthparts are designed for piercing and sucking sap from plants.
- No Disease Transmission: There is no evidence to suggest that spotted lantern flies can transmit diseases to humans.
2.2 Potential Harm to Pets
- Non-Toxic: There is no scientific evidence indicating that spotted lantern flies are toxic to pets if ingested.
- Nuisance: Some anecdotal reports suggest that pets may experience mild gastrointestinal upset if they eat spotted lantern flies, but this is not a common occurrence.
3. The Real Danger: Impact on Plants and Ecosystems
The primary concern with spotted lantern flies is their impact on plants and ecosystems. They feed on a wide range of host plants, including economically important crops and native trees.
3.1 Host Plants
Spotted lantern flies feed on over 70 different plant species, including:
- Fruit Trees: Apples, grapes, peaches, and plums
- Hardwood Trees: Maple, oak, and walnut
- Other Plants: Hops, soybeans, and ornamental trees
3.2 How They Damage Plants
Spotted lantern flies damage plants by:
- Sucking Sap: They use their piercing mouthparts to extract sap from plant stems and leaves, weakening the plant.
- Producing Honeydew: They excrete a sugary substance called honeydew, which promotes the growth of sooty mold.
- Attracting Other Pests: Honeydew attracts other insects like ants and wasps, which can further damage plants.
3.3 Economic Impact
The economic impact of spotted lantern flies can be significant:
- Crop Losses: Infestations can lead to reduced crop yields and quality, impacting farmers’ income.
- Control Costs: Managing spotted lantern fly infestations requires resources for monitoring, treatment, and prevention.
- Property Value: Heavy infestations can reduce property values due to damage to trees and ornamental plants.
According to a 2019 study by Pennsylvania State University, if the spotted lantern fly isn’t contained, they could drain the state’s economy by up to $324 million each year and cause the loss of 2,800 jobs.
4. Spotted Lantern Fly Infestation: Signs and Symptoms
Identifying a spotted lantern fly infestation early can help prevent further damage. Look for these signs:
4.1 Egg Masses
- Appearance: Mud-like coverings on trees, rocks, and other surfaces.
- Location: Often found on the trunks of trees, branches, and underside of objects.
4.2 Nymphs
- Appearance: Small, black with white spots (early instars) or red and black with white spots (later instars).
- Behavior: Often found feeding on plant stems and leaves in large numbers.
4.3 Adults
-
Appearance: Large, distinctive wings with gray and black spots (forewings) and red, black, and white patterns (hindwings).
-
Behavior: Flying around host plants, feeding, and mating.
4.4 Honeydew and Sooty Mold
- Honeydew: Sticky, sugary substance on plants and surrounding surfaces.
- Sooty Mold: Black, sooty growth on plants, caused by fungi feeding on honeydew.
5. How Do Spotted Lantern Flies Spread?
Spotted lantern flies can spread through both natural and human-assisted means. Understanding how they spread is crucial for preventing new infestations.
5.1 Natural Spread
- Flight: Adult spotted lantern flies can fly short distances, allowing them to move between nearby plants and areas.
- Wind: Strong winds can carry nymphs and adults to new locations.
5.2 Human-Assisted Spread
- Transportation of Egg Masses: Egg masses can be unknowingly transported on vehicles, firewood, outdoor furniture, and other items.
- Movement of Infested Plants: Moving plants infested with spotted lantern flies can introduce them to new areas.

6. How to Control and Manage Spotted Lantern Flies
Controlling spotted lantern flies requires a multi-faceted approach that includes prevention, monitoring, and treatment. Here are some effective strategies:
6.1 Prevention
- Inspect and Remove Egg Masses: Scrape off egg masses from trees, vehicles, and other surfaces. Dispose of them in a sealed bag.
- Avoid Moving Infested Materials: Be cautious when moving firewood, outdoor furniture, and other items that may harbor spotted lantern flies.
- Use Tree Bands: Wrap tree trunks with sticky bands to trap nymphs as they climb.
6.2 Monitoring
- Regular Inspections: Regularly inspect host plants for signs of spotted lantern flies.
- Report Sightings: Report any sightings of spotted lantern flies to your local Department of Agriculture or Extension office.
6.3 Treatment
- Insecticides: Use insecticides to control spotted lantern flies on heavily infested plants. Follow label instructions carefully.
- Tree Removal: Remove heavily infested trees, especially Tree of Heaven (Ailanthus altissima), which is a preferred host.
- Biological Control: Encourage natural predators like birds, spiders, and parasitic wasps.
6.4 Government Regulations
- Quarantine Zones: Numerous counties in affected states have implemented quarantine zones, where there are rules and permits needed for moving items in, out and within these areas.
