What You Need To Know About the Spotted Lanternfly

April 28, 2021

What is the spotted lanternfly? Chances are if you live in Pennsylvania, you already have seen this insect. The spotted lanternfly is an invasive species native to China and other Southeast Asian countries. The pest was discovered in Berks County in 2014 and has spread throughout Pennsylvania. The spotted lanternfly feeds on many different plants and has caused massive damage to the environment in Pennsylvania. Many homeowners have reported sightings and damage due to this pest.. Here is what you need to know about this invasive species and what you can do if you spot the colorful insect around your property.

What You Need to Know About the Spotted Lanternfly

The spotted lanternfly is currently reported to be found in 34 Pennsylvania counties and has caused massive damage to those counties’ environments. While many Pennsylvania residents have spotted this invasive species on their landscapes, we have some information to help those who want to keep their landscape free from invasive species.

Appearance

Adult spotted lanternflies can be identified from their coloration and bodies. The insect has grayish wings with black spots, and the tips are black and gray, while the bodies are black. When flying, spotted lanternflies will show vibrant red hind wings. Adults are around 1 inch long and a half-inch wide with wings folded. They can jump several feet when startled or approached.

You can also identify the pest via their egg masses or nymph stage. Egg masses are typically found on tree bark or other smooth surfaces such as rocks, outdoor furniture, and even vehicles. The mass is usually around 1 inch long and a half to three-quarters of an inch wide, with a gray-brown, mud-like covering. Spotted lanternfly nymphs are much smaller than adults, only about ½ an inch long, but have distinct coloration: initially black with white spots and wingless, developing red patches and white spots as they mature.

Behavior & Problems

Spotted lanternflies feed on plant sap, and at a high population, this can cause significant damage to an area’s plant life. While known to feed on over 70 different plants, spotted lanternflies have shown a preference for the tree of heaven, or ailanthus tree, as well as grapevines, maple trees, black walnut, birch, willow, and other trees. Feeding on tree and plant sap can cause wilting, leaf curling, and dieback. As the spotted lanternfly feeds on plant sap, the insect excretes a sugary substance called “honeydew,” which can attract bees, wasps, other insects and promotes the growth of sooty mold, which causes further damage to plants.

To help you better identify the plant pest, here are the months that each life occurs.

  • Egg masses: The invasive pest will usually lay eggs from September to November, getting ready to hatch around May.
  • Nymphs: Nymphs will first hatch around May to June and mature until around July to September.
  • Adults: July to December is when most spotted lanternflies have matured into adults, ready to lay new eggs and repeat the cycle.

The insect has become so prevalent that Pennsylvania has put affected counties under quarantine to stop the movement and slow the insect’s spread to new areas within or out of the current quarantine zone. The quarantine involves traveling and transporting outdoor items.
