The invasive plant-hopping Spotted Lanternfly, indigenous to Asia, has made its way to the eastern U.S., probably via a cargo ship from Asia in 2012 into Philadelphia. It has since migrated into 19 eastern states. It will eventually hop a train, or some other mode of transportation, to the rest of the country.
Its reproductive rate and ability to live off of many plants, makes it is unlikely that we can eradicate the Lanternfly. This is bad news.
