Adult spotted lanternflies are 1″ long and 1/2″ wide at rest. Their forewings are grey with black spots, while the hind wings are red and black. Their legs and heads are also black, and their abdomens are yellow with broad black bands. Early stages (nymphs) are mostly black with small white spots and become red during maturation.

What Do They Do?

Spotted lanternflies quickly jump and fly from plant to plant to reach food and lay eggs. Spotted lanternflies feed on plant sap, preferring Ailanthus trees (tree of heaven), through a straw-like appendage in their mouth. The insects will hop from plant to plant, feeding until around late September when mating and egg laying begins. These eggs typically hatch in the spring, and the nymphs will feed on trees until becoming adults, then the cycle continues. Spotted lanternflies do not chew, bite, or have stingers, so people are safe around them, but some trees are not.

The Impact & Danger of Spotted Lanternfly

One reason we want to inform our community of spotted lanternfly facts is the danger those insects possess. The spotted lanternfly is an invasive species in the United States and has caused a massive impact on peoples’ trees and properties, particularly on the east coast.

What Does Spotted Lanternfly Do To Trees?

That sap provides much-needed nutrients to trees, and by feeding on that sap, the spotted lanternfly makes trees weaker and more vulnerable to other harmful insects or diseases. In addition to feeding on the sap, spotted lanternflies also excrete a sugary substance called honeydew, which can attract other insects and promote a fungus called sooty mold.

What Is The Impact of Spotted Lanternfly?

The overall impact of spotted lanternflies has been enormous. In Pennsylvania alone, their damage to trees could cost the state roughly $325 million annually. As of March 2021, 34 Pennsylvania counties are in quarantine for the spotted lanternfly, primarily the eastern, southeastern, and south-central PA counties. One reason why spotted lanternflies have been so devastating to many peoples’ trees is the way the pest spreads and migrates from tree to tree.

How Does Spotted Lanternfly Spread?

The spotted lanternfly has spread across the United States for many reasons. These insects can lay eggs on nearly any surface, from trees to wooden decks and patios to even cars or pipes. This ability to lay eggs on different surfaces means that some people can inadvertently transport the eggs across counties or even states. Below are some of the objects spotted lanternfly has been known to lay eggs on:

  • Firewood
  • Construction or landscaping materials
  • Outdoor equipment or furniture
  • Crates or boxes

Because the spotted lanternfly is an invasive species, none of the natural predators that would keep its population in control in its native environment are present in the U.S. This factor means the insect can spread more quickly.

What Can You Do To Help?

As a homeowner, you can do a few things to help slow down the spread of spotted lanternfly to keep your trees safe and beautiful:

  1. Be diligent and watch for any signs of spotted lanternflies, whether they are adults, nymphs, or egg masses.
  2. Take measures to prevent transporting any of the items listed previously that spotted lanternfly lay their eggs on, and always check for egg masses before traveling.
  3. Reach out to a professional, certified arborist who can examine your property for any signs of this invasive species and who can advise you on the best course of action to keep your trees healthy and safe.
