The spotted lanternfly (Lycorma delicatula) is an invasive species that threatens ecosystems and agriculture. First found in Pennsylvania in 2014, it quickly spread across multiple states, harming crops, trees, and plants. “The host plant is generally weaker after the lanternfly feeds on its sap, making it more likely to get sick or stressed from outside sources.” The bug also secretes honeydew, which promotes sooty mold, further damaging plants.

Lanternflies are easily recognizable. “Insect wings that are fully grown are gray with a brownish background and lots of black spots.” Their underwings feature a striking red-and-black pattern. Nymphs are black with white spots and turn red before adulthood. Using their needle-like mouthparts, they extract plant fluids, weakening trees like maples, grapes, and pears.

To control the lanternfly, swift action is necessary. “If you squash the nymphs and adults, you can get rid of them quickly.” Destroying egg masses, which resemble muddy streaks on trees and rocks, is also crucial.

Lanternflies harm agriculture and urban greenery, reducing crop yields and disrupting ecosystems. Since they lay eggs on vehicles and outdoor objects, checking and cleaning items before traveling helps prevent their spread.

Public awareness and action are key. “Our natural resources may be saved and the lanternfly’s damage to them may be lessened if we all do our part.”
