Few causes have united the country like this summer’s multistate effort to kill spotted lanternflies, the colorful invasive insects that have wreaked havoc in at least 14 states. Now, as adult lanternflies begin to perish during the winter, experts say those efforts might have curbed the species’ spread to some degree. Anne Johnson, a doctoral student studying the spotted lanternfly in Hoover’s lab at Penn State, believes the viral trends can make a difference. Spotted lanternflies are native to China, where they don’t often become a pest. “We’ll always have to deal with spotted lanternfly,” Johnson said.
