Spotted Lanternfly

Natural Habitat

Found in agricultural areas, vineyards, orchards, and forests, particularly preferring Tree of Heaven (Ailanthus altissima) as a host plant, but also infests a wide range of other trees and plants.

Diet & Feeding

Feeds by piercing plant tissues with its mouthparts to suck out sap. It feeds on over 70 plant species, including economically important crops like grapes, apples, hops, and various hardwoods.

Behavior Patterns

Adults are active from July to December, laying egg masses (containing 30-50 eggs) on smooth surfaces such as trees, rocks, outdoor furniture, and vehicles. Nymphs hatch in spring and go through four instar stages. They are known for their swarming behavior and ability to excrete large amounts of honeydew, which promotes the growth of sooty mold.

Risks & Benefits

Significant agricultural pest, causing severe damage to crops, especially vineyards and fruit trees. The honeydew excretion can also damage plants and cover surfaces, leading to aesthetic and structural issues. There are no known benefits, and it poses a substantial economic risk to affected industries.
