The Spotted Lanternfly,Lycorma delicatula (White), an invasive planthopper, has been discovered in Eastern Pennsylvania. This insect, which is native to China, India, & Vietnam, feeds on a wide range of plants and trees. This non-native plant hopper attacks many hosts and has the potential to greatly impact the grape, fruit tree, and logging industries.
The U.S. Department of Agriculture (USDA) and their state cooperators need your help in detecting the spotted lanternfly. Early detection is vital for the protection of Pennsylvania businesses and agriculture.
Learn about its life cycle and habits
Eggs are laid in late fall and hatch in the spring. Throughout the year, you could be seeing both adults that emerged in July and remain active until winter, along with newly laid eggs. Egg masses are laid on trees, decks, houses, and other hard surfaces and are protected by a mud-like covering. SLF adults are the most detectable stage since they are large, brightly colored, and mobile.
Manage the Pest's Invasion
There are two major steps you can do to stop the spread of SLF. The first step is to check your car and any outdoor equipment (grills, mowers, firewood, etc.) when you go in and out of Montgomery County. If you find SLF eggs, nymphs, and adults,do not transport them out of the quarantine zone.
The second step is to manage the SLF on your own property. To do this, you should scrape the eggs and dispose of them, band trees to catch nymphs, remove the favored host tree (tree-of-heaven), and use insecticides when appropriate.
