Understanding the Lanternfly
The lanternfly, despite its somewhat charming name, is a significant threat to both agriculture and local ecosystems. Native to China, this insect was first detected in the United States in Pennsylvania in 2014. Since then, it has spread across numerous states, causing considerable damage to crops and ornamental plants alike. Its ability to devastate both commercial farms and private gardens makes it a pest of considerable concern.
The Damage They Cause
Lanternflies feed on the sap of various plants and trees using their long, needle-like mouthparts. This feeding process not only weakens the plants but also excretes a sticky substance known as honeydew. The honeydew promotes the growth of sooty mold, which can cover the plant’s leaves and inhibit photosynthesis. As a result, the plants are unable to produce the oxygen they need to thrive, leading to their eventual decline. In my own experience, the once vibrant leaves of my maple tree became dull and dark as the mold spread.
