The spotted lanternfly has now spread throughout New Jersey, currently seen in both the nymph and adult stages from July - September. They are a threat to both New Jersey and the United States, laying egg masses of 30-50 eggs wherever it chooses, especially on flat surfaces. All other life stages of this insect, from nymphs to adults can fly, hop, or drop right into or onto vehicles – meaning that vehicles and equipment can easily and quickly help it spread.
This insect has the potential to significantly impact agricultural crops and hardwood trees. The spotted lanternfly feeds on the plant sap of many different plants including grapevines, maples, black walnut, and other important plants in NJ. While it does not harm humans or animals, it can reduce the quality of life for people living in heavily infested areas.
The spotted lanternfly is a serious invasive pest with an appetite for plants and it can be a significant nuisance, affecting the quality of life and enjoyment of the outdoors. The spotted lanternfly uses its piercing-sucking mouthpart to feed on sap from over 70 different plant species. It has a strong preference for economically important plants and the feeding stresses and damages the plants.
As the spotted lanternfly feeds, the insect excretes honeydew (a sugary substance) which can attract bees, wasps, and other insects. The honeydew also builds up and promotes the growth for sooty mold (fungi), which can cover the plant, forest understories, patio furniture, cars, and anything else found below the feeding insect.
