Need Spotted Lantern Fly Inspection in Downingtown, PA?
The Spotted Lanternfly is an invasive planthopper that has been discovered in Downingtown, PA. This invasive pest is native to Southeast Asia and was imported to Pennsylvania. They are spreading rapidly and present a serious threat to gardens, orchards, and woodlands. Early detection of this invasive pest is the key to protecting crops such as grapes, apples, stone fruits, and hardwoods.
Spotted Lanternfly Life Cycle
Adult Spotted Lanternflies are approximately 1” long and 1/2” wide. The forewing is gray with black spots and the wing tips are striped in black and gray. The hind wings have contrasting patches of red and black with a white band. While it has two pairs of wings, the lanternfly is a strong jumper and hops more than it flies. 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. In the spring, egg masses hatch into tiny, 1/8″ black and white nymphs which are incapable of flight. As the spring progresses, the nymphs pass through four stages, growing with each molt. The first three stages are black with white spots, the fourth stage is orange with black and white spots. Adults begin appearing in early summer.
Egg masses are attached to trees, walls and other surfaces.
Young nymphs start dark in color and feed on soft plant tissue.
Mature nymphs turn red after molting while continuing to feed.
Winged adults fly from tree to tree to feed, breed and lay eggs.

Symptoms of Infested Plants
Nymphs first feed on small plants and vines in the spring using their piercing mouthparts to suck the sap out of stems, leaves, and even the trunks. After maturing into adults, Spotted Lanternflies begin feeding on trees. Infested trees develop weeping wounds which leave grayish or black trails along the trunk. As they feed, a sticky substance called honeydew is excreted.The sap then attracts mold and other insects to feed, notably ants, bees and wasps. In fall, adults lay egg masses on host trees and nearby smooth surfaces like outdoor furniture, stone, structures and vehicles. Newly laid egg masses have a gray mud-like covering which can take on a dry cracked appearance over time. Old egg masses appear as rows of 30-50 brownish seed-like deposits in 4-7 columns on the trunk, roughly an inch long.
