Spotted lanternflies are about 1 inch long and have a wingspan of 2 inches. Their hind wings are bright red with black spots, while the front wings are transparent with black markings near the edge. This large leaf hopper-type insect lives on the sap of many species and literally sucks the life out of them. It also leaves behind a sticky residue known as 'honeydew' that attracts more insects, creates destructive sooty mold, and causes staining. Weaker, stressed trees are more susceptible to disease and becoming infested by other insects. And while spotted lanternflies are a greater threat to agricultural crops, they still cause notable issues for the health of trees in an urban environment as well.
Lanternflies lay egg masses containing 30–50 eggs, often covered with a grayish mud-like coating
The bug threatens about 70 tree species, including pines, walnuts, maples, and oaks. Its preferred host is another invasive species called the tree of heaven.
