Across New York City, large marks and smears of red-like paint are lining the streets. They’re appearing throughout tourist hotspots like Times Square and Central Park. From roads to pavements, even within supermarkets. These marks are the remains of the spotted lanternfly (Lycorma delicatula).
The spotted lanternfly (Lycorma delicatula) is an emerging insect pest of a number of economically important crop plants. Originating from China, its primary host plant is tree of heaven (Ailanthus altissima), which is itself considered to be a noxious invasive species in some areas of the United States.
