Spotted lanternfly

A native of Southeast Asia, the spotted lanternfly was first discovered in Pennsylvania in 2014. Historically an agricultural pest, the spotted lanternfly is known to wreak havoc on fruit trees, grapevines, and ornamentals. This invasive species has the potential to damage trees for both homeowners and business operators alike.

While agriculture was their initial target, spotted lanternfly have quickly found new homes: our backyards, landscape, gardens, orchards, woodlands and community landscapes. If left untreated, the spotted lanternfly can reproduce rapidly, leaving risk for a heavy infestation, and can begin to damage your landscape and garden.

Egg mass

Found September - May

Egg masses are laid on hard surfaces outdoors and can be hard to identify, as they can blend in with their surroundings. The egg masses are covered with a grey mud-like substance, giving them a mortar-like appearance.



Found April - October

The nymph stage consists of four developmental stages, called instars. In these stages, nymphs will grow from ⅛” to ½”. At first, the nymphs are soft and white, and then in the middle instar stages, they are black with white spots. In their final stage, nymphs are red and black with white spots. Nymphs can be found climbing trees and shrubs.



Found July - November

Spotted lanternfly adults are large, about one inch long, and have black bodies with brightly colored wings. Only adults can fly, however, they jump more than they fly, so their wings are often closed. Lanternfly wings are gray with black spots, and the tips of the wings are black with gray veins.


What you need to know about the spotted lanternfly


Spotted lanternflies prefer to live on plants and trees, including ornamental, woody, and fruit trees; vegetables; herbs; grains; and vines. Their preferred host is the Tree of Heaven.


There is one generation of spotted lanternfly each year. Spotted lanternflies lay their eggs in the fall, which then hatch in the spring. Each egg mass contains 30–50 eggs. Once hatched, the spotted lanternfly goes through four nymph stages. Adults emerge in July and are active until winter.


Spotted lanternflies feed on the sap of leaves, stems, and trunks of plants and trees. They end up sucking in more sap than they can handle, causing them to excrete the rest of it. This excretion is a sticky substance that can grow mold and attract other insects.
