The Spotted Lanternfly Information
The Spotted Lanternfly, Lycorma delicatula is a new pest to the United States. This invasive plant hopper, initially discovered in Berks County, Pennsylvania in 2014 is native to Southeast Asiaand poses a threat to forests, ornamental trees, orchards, vegetables, grapes,hops and other agricultural commodities. Since its initial discovery in Pennsylvania it has spread to infest portions of 13 counties of that state,recently it has been discovered in New Jersey in Warren, Hunterdon and Mercer Counties. The New Jersey Department of Agriculture has recently enacted a state quarantine in these counties to restrict the movement of this insect to un-infested areas of the state. 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.
The New Jersey Department Of Agriculture is asking residents to be aware of this insect and report sightings by calling the Spotted Lanterfly Hotline 1-833-223-2840 and leave a message with details of the sighting and contact information or by emailing SLFfirstname.lastname@example.org
