Here in Maryland, we are still shell shocked from the smelly Stink Bug Invasion and we need to get ready for an even worse invasive species that is making its home here on the East Coast. Starting just four years ago in Bucks County Pennsylvania when a shipment of stone from Asia arrived with Lanternfly eggs attached, the Spotted Lanternfly (Lycorma delicatula) is native to China and was first detected in Pennsylvania in September 2014.
Spotted Lanternfly is a one inch long plant hopper who feeds on ornamental and fruit trees, with Ailianthus, or Tree of Heaven, another invasive, its preferred hosts. Smelling like well-used gym socks, this tree appears everywhere along roads, in cracks of sidewalks, and anywhere it drops a seed. Signs of an infestation are weeping wounds that leave a greyish or black trail along the trunk. Weeping sap attracts other insects to feed, notably wasps and ants. Egg masses are laid on host trees and other smooth surfaces like stone, outdoor furniture, vehicles, and structures in late Fall.
Spotted Lanternflies are invasive and can be spread long distances by people who move infested material or items containing egg masses.
Just spotted recently in Cecil County, Maryland, this noxious pest is poised to spread throughout Maryland in the next couple of years. Orchards and vineyards will be the first to be invaded and they will spread from there to homes.
According to the Pennsylvania Department of Agriculture, the spotted Lanternfly has been spotted in 13 counties of Pa- Berks, Bucks, Carbon, Chester, Delaware, Lancaster, Lebanon, Lehigh, Monroe, Montgomery, Northampton, Philadelphia and Schuylkill. My first sighting of the Lanterfly was at a friends house in Montgomery County, PA, when I spotted one perched on the side of the house.
Since it is new to the United States, little is known about its behavior and biology, but researchers are feverishly gathering information and scientific data on how to manage this pest. Aerial spraying is not an option as large-scale spraying of this type can kill native species and cause more harm to the environment.
Right now, the recommendation is to destroy the bug or egg mass to stop the spread. Adults will lay egg masses on host trees and nearby smooth surfaces like stone, outdoor furniture, vehicles, and structures.
