Scientific Name:Lycorma delicatula
Common Names: Spotted lanternfly

Known Hosts:
The spotted lanternfly is found on a wide range of plants, including grape (Vitis spp.), the invasive tree of heaven (Ailanthus altissima), apple (Malus spp.), plum (Prunus spp.), pine (Pinus spp), and 65 other plants. The nymphs of this species tend to be less picky about host plants, whereas the adults tend to prefer tree of heaven to feed on and lay their eggs.

Key ID Features
Adults have brownish-gray forewings with black spots, and appear dull when at rest. (Figure 1)
When disturbed, the lanternfly will hop or fly away, revealing bright red and white hindwings. (Figure 2)
Overwinters as a gray egg mass laid on any smooth flat surface. The egg mass resembles mud. (Figure 3)
The first 3 instar nymphs are black with varying amounts of white speckling. The final, fourth instar nymph is red, black and white. The nymphs can be found on host plants, often feeding on the softer parts of the plants. (Figure 4)
Description of damage
Adults and nymphs of this species cause significant damage by feeding on sap from the stems, leaves, and trunks of the trees.
Adult lanternflies damage trees by feeding on the sap and excreting honeydew. The honeydew then causes sooty mold and attracts other insects that may also cause damage to the plant.
Current Distribution
Spotted Lanternfly was first discovered in Berks County, Pennsylvania in September of 2014. It has since spread to 13 counties in Pennsylvania and is under a quarantine in that state. It was also found in both Delaware and New York in late 2017.

As of January 2018, Spotted Lanternfly has not been found in Massachusetts.
Similar Species or Symptoms
