The spotted lanternfly is a potentially serious problem for farmers in the Northeast, no doubt. The invasive species (it is native to southeast Asia) is considered an especially worrisome threat to the grape, tree-fruit, hardwood and nursery industries. In Pennsylvania, the state has quarantined counties where it’s been observed (meaning local businesses that deal with fly-infested products are closely supervised). Billions of dollars of goods are at stake. And most worrisome, for the first time a spotted lanternfly was found in Maryland, specifically in the northeast corner of Cecil County last fall. Officials do not believe the population has yet taken hold in the state, but the potential is obviously there.
