The Spotted Lanternfly’s physical appearance transforms throughout its life stages as it matures to adulthood. Right now there are nymphs present and the adults are coming soon. Be sure to step on and kill any of these insects you see!
This destructive insect has the potential to greatly impact agricultural crops and hardwood trees. While the Spotted Lanternfly prefers the Tree of Heaven (Ailanthus altissima), it feeds on the plant sap of a variety of host plants including fruit trees, ornamental trees, woody trees, vegetables, herbs, grains and vines. It has a strong preference for economically important plants and the feeding damage signiﬁcantly stresses the plants which can lead to decreased health and potentially death. As SLF 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 SLF feeding. While it does not harm humans or animals, it can reduce the quality of life for people living in heavily infested areas.
