The spotted lanternfly (Lycorma delicatula) is an invasive insect that has seriously threatened trees, agriculture, and the environment in various parts of the United States, particularly in Pennsylvania. Strobert Tree Services is committed to providing valuable information on identifying, preventing, and treating infestations of this destructive pest. In this article, we will explore what spotted lanternflies are, how to identify their eggs, which trees they affect, the damage they cause, and most importantly, how to get rid of them effectively.
What is a Spotted Lanternfly?
Despite its name, the spotted lanternfly is not a fly but rather an insect. It is native to Southeast Asia and was first detected in the United States in Pennsylvania in 2014. This invasive species has rapidly spread and significantly threatens various plants, including trees, shrubs, and agricultural crops.
The adult spotted lanternfly is about one inch long, with striking features that include red and black wings with white spots and a bright red abdomen. These distinctive colors make it relatively easy to identify when in its adult stage. However, managing this pest often involves dealing with its various life stages, including the egg stage.
How to Identify Spotted Lanternfly Eggs
One of the keys to managing spotted lanternfly infestations is early detection, which includes identifying their eggs. Lanternfly egg masses are laid in the fall and throughout the winter months.
Here's how to identify them:
1. Look for Gray, Putty-Like Masses: Spotted lanternfly eggs are laid in masses that resemble gray, putty-like substances. These masses can be found on various surfaces, including tree trunks, branches, and man-made structures like fences and vehicles.
2. Check for a Slight Yellowish Tint: The egg masses may have a slight yellowish tint. They are often covered in a mud-like substance for protection.
3. Size and Shape: These masses are typically about one inch long and half an inch wide, but they can vary in size. Small nymphs emerge When the eggs hatch and can infest nearby plants.
If you come across spotted lanternfly egg masses, it's crucial to take action to prevent them from hatching and spreading.
What Trees are Affected by Spotted Lanternfly
Spotted lanternflies have many host plants, including trees, vines, and ornamental plants. Some of the trees most commonly affected by these pests include:
1. Ailanthus (Tree of Heaven): Spotted lanternflies are particularly drawn to the Tree of Heaven, often used as their primary host.
2. Fruit Trees: They also target fruit trees like apple, cherry, and plum, which can devastate orchards.
3. Hardwood Trees: Oak, maple, and walnut trees are among the hardwood trees that can suffer significant damage.
4. Ornamental Trees and Shrubs: Many ornamental trees and shrubs, such as roses and azaleas, are susceptible to spotted lanternfly infestations.
It's crucial to monitor these trees and plants for signs of infestation and take preventive measures to protect them.
Spotted Lanternfly Tree Damage
Spotted lanternflies cause damage by feeding on the sap of trees and plants, resulting in a variety of negative effects:
1. Weakened Trees: The continuous feeding weakens the trees, making them more susceptible to diseases and other pests.
2. Reduced Crop Yield: Spotted lanternflies can significantly reduce crop yields by feeding on fruit trees and vines in agriculture.
3. Honeydew Production: Lanternflies excrete a sugary substance called honeydew, which can attract other pests like ants and mold, further harming plants.
4. Environmental Impact: The damage caused by spotted lanternflies can have cascading effects on the environment, disrupting ecosystems and affecting wildlife.
How to Get Rid of Spotted Lanternfly
- Scraping Egg Masses: In late fall and winter, scrape spotted lanternfly egg masses off trees, rocks, or other surfaces where they are laid. Dispose of them by placing them in a plastic bag with rubbing alcohol or burning them.
- Use Sticky Bands or Tape: Wrap tree trunks with sticky bands or tape during the nymph stage to capture crawling lanternflies. This can help reduce their population.
- Chemical Control: If infestations are severe, consider using insecticides labeled for spotted lanternfly control. Following the instructions and safety precautions on the product label is essential.
- Tree Banding: Banding trees with sticky tape during the adult stage can capture lanternflies as they climb up the tree to feed.
- Natural Predators: Encourage natural predators like birds, spiders, and praying mantises, which can help control lanternfly populations.
What Eats Spotted Lanternfly? Several natural predators of spotted lanternflies include birds, spiders, and mantises. Encouraging these predators in your area can help control lanternfly populations.
Are Lanternflies Dangerous? While spotted lanternflies are not dangerous to humans, they pose a significant threat to agriculture, trees, and the environment due to their feeding habits and ability to multiply rapidly.
Why Are Lanternflies Bad? Spotted lanternflies are considered bad because they can cause extensive damage to trees, plants, and crops. They disrupt ecosystems and negatively impact local industries.
Where Do Spotted Lanternflies Go at Night? Spotted lanternflies are most active during the day and typically rest on trees, plants, or other surfaces at night.
