The spotted lanternfly (Lycorma delicatula) was first identified in Berks county Pennsylvania in 2014. This invasive planthopper, which is native to China, Bangladesh and Vietnam, can now be found in 14 states including Connecticut, Delaware, Indiana, Maryland, Massachusetts, Michigan, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Rhode Island, Virginia and West Virginia. The spotted lanternfly is an excellent hitchhiker and can easily be introduced to new areas by movement of infested materials. We recommend that neighboring areas scout for spotted lantern fly as it will likely continue to spread.
These pests damage trees causing oozing sap, wilting, leaf curling and tree dieback. They also excrete a sugary substance when they feed, called honeydew, that promotes the growth of black sooty mold, which damages plants and can cover patio furniture, cars and more. These insects also affect quality of life and the ability to enjoy the outdoors during the spring and summer as they cover trees, swarm in the air and coat decks and play equipment with honeydew, which is an attractant to other unwanted pests like ants and wasps.
In addition to damaging trees and affecting quality of life, spotted lanternflies are a huge threat to the agriculture industry. They damage crops such as grapes, apples, hops and hardwood trees.
An adult spotted lanternfly is approximately one inch long and half an inch wide. The forewing is grey with black spots and the wings tips are reticulated black blocks outlined in grey. The hind wings have contrasting patches of red and black with a white band. The legs and head are black; the abdomen is yellow with broad black bands. Immature stages are black with white spots and develop red patches as they grow.
