Lycorma delicatula, commonly known as the Spotted Lanternfly, is a new invasive insect that has spread throughout southeastern Pennsylvania since its discovery in Berks County in 2014. It presents a significant threat to Pennsylvania agriculture, including the grape, tree-fruit, hardwood and nursery industries, which collectively are worth nearly $18 billion to the state's economy.
Montgomery County is currently under quarantine. Last year, quarantines were imposed by individual munipalities. However, due to the rapid spread of the insect quarantines are now designated by county. If you see a Spotted Lanternfly in Montgomery County you are no longer asked to report it.
What is WVWA doing?
WVWA is actively working to remove Tree-of-heaven (Ailanthus altissima) from our properties. This tree is the preferred host plant of the Spotted Lanternfly. As recommended, we are also scraping any eggs that we come across while working in the field.

The most important thing you can do is make sure you are not inadvertently transporting them across county or state lines. PennState Extension and the Department of Agriculture have very comprehensive webpages devoted to the Spotted Lanternfly.
On the websites you will find information about:
