Understanding and Combating the Spotted Lanternfly
What Is the Spotted Lanternfly?
The spotted lanternfly (Lycorma delicatula) is an invasive pest native to Southeast Asia that has rapidly spread across parts of the United States, causing significant ecological and agricultural damage. Known for its striking appearance, this pest features gray wings with black spots and a vibrant red underlayer visible during flight. While visually captivating, the spotted lanternfly is anything but harmless—it poses a severe threat to trees, plants, and agricultural crops, including grapes, apples, and hardwood trees.
Why Is the Spotted Lanternfly a Concern?

The primary concern with the spotted lanternfly is its ability to damage and weaken plants by feeding on their sap. This feeding process disrupts the flow of nutrients within the plant, leaving it vulnerable to disease and other environmental stressors. Additionally, the insect excretes a sticky substance called honeydew, which encourages the growth of sooty mold. This mold can further compromise plant health and create a mess in residential landscapes, patios, and outdoor furniture.
For residents and businesses in the San Francisco Bay Area, preventing the establishment of invasive species like the spotted lanternfly is essential. While this pest has not yet been detected in California, proactive measures can help reduce the risk of infestation.
How Does the Spotted Lanternfly Spread?
Spotted lanternflies are highly mobile, capable of hopping and gliding short distances. However, the primary way they spread to new areas is through human activity. They often lay their egg masses on vehicles, shipping materials, firewood, and outdoor furniture, which can inadvertently transport them across state lines. Each egg mass can contain 30–50 eggs, making them a major concern for spreading rapidly.
Identifying Spotted Lanternfly Infestations

Recognizing the early signs of a spotted lanternfly infestation is crucial for controlling its spread. Here’s what to look for:
- Egg Masses: These appear as grayish, mud-like patches on surfaces such as tree trunks, rocks, and outdoor equipment.
- Nymphs: The immature stage is black with white spots and transitions to red as it matures.
- Adults: Fully grown spotted lanternflies are approximately one inch long and display their distinctive spotted wings.
- Honeydew and Sooty Mold: Look for sticky residue on plants or black mold growing on leaves, bark, or nearby surfaces.
Preventing the Spread of the Spotted Lanternfly
Proactive measures are the best defense against the spotted lanternfly. Here are some steps you can take to protect your landscape and community:
- Inspect and Remove Egg Masses: Regularly check trees, outdoor furniture, and vehicles for egg masses. Scrape them off into a container filled with rubbing alcohol or soapy water to kill the eggs.
- Be Cautious with Firewood: Avoid transporting firewood across state lines, as it may harbor egg masses. Use locally sourced firewood whenever possible.
- Report Sightings: If you believe you’ve spotted a spotted lanternfly or its egg masses, report it to your local agricultural extension office or the California Department of Food and Agriculture (CDFA).
