This approximately 1-inch-long species from Asia has attractive polka-dotted front wings but can infest and kill trees and plants. We recently caught up with Professor Frank Hale, an entomologist who is tracking this species.
The Conversation: How did the spotted lanternfly get to the U.S., and how quickly is it spreading?
Frank Hale: It is native to India, China and Vietnam and probably arrived in a cut stone shipment in 2012. The first sighting was in 2014 in Berks County, Pennsylvania, on a tree of heaven—a common invasive tree brought to North America from China in the late 1700s.
By July 2021 the lanternfly had spread to about half of Pennsylvania, large areas of New Jersey, parts of New York state, Maryland, Delaware and Virginia. It also had been found in western Connecticut, eastern Ohio, and now Indiana.

To give an idea of how fast these lanternflies spread, they were introduced into South Korea in 2004 and spread throughout that entire country—which is approximately the size of Pennsylvania—in only three years. READ MORE
