Spotted Lanternfly Lycorma delicatula

Beautiful to look at but devastating in practice: this planthopper was accidentally introduced from China and Vietnam and has spread invasively across the US, Japan, and South Korea with alarming speed. It's a crop killer—feeding on grapes, stone fruits, soybeans, and other valuable plants with voracious appetite. Here's the twist: in its native habitat, parasitic wasps keep populations in check. Without its natural enemies in new territories, this insect has become a nightmare for farmers worldwide, proving that invasive species need their ecological context to stay balanced.
