NJ Spotted Lanternfly Quarantine Regulation
Spotted Lanternfly (SLF), Lycorma delicatula, is an invasive planthopper native to China, India, and Vietnam, it is also established in South Korea, Japan and the U.S. It was first discovered in the U.S. in Pennsylvania in Berks County in 2014 and has spread to other counties in Pa., as well as the states of New Jersey, Delaware, Maryland, Virginia and West Virginia. This insect has the potential to greatly impact agricultural crops and hardwood trees. 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 evolves through life stages as it matures. Below is a look at those stages.
There are four nymphal instars. The first three instars are black with white spots and wingless. They appear in this stage beginning in the spring and through early July.
The fourth instar has red wing pads and an upper body. They appear in this stage from about mid-July through mid-August.
The forewing is gray with black spots of varying sizes and the wing tips have black spots outlined in gray. They become full-grown adults in about mid-August.
The legs and head are black, and the abdomen is yellow with black bands.
Hind wings have contrasting patches of red and black with a white band.
While adult the adult Spotted Lanternfly does not survive the winter, the egg masses do. Egg masses contain 30-50 eggs. Females can lay up to two eggs masses.
An egg mass is approximately 1 inch in size and 80 to 90 percent of egg masses on trees are found 10 feet above the ground.
