In 2014, the appearance of a strange bug near Pennsylvania set off alarm bells. Eventually identified as the spotted laternfly, it’s become one of the fastest-spreading invasive species in the US. And if left unchecked, it could cost states hundreds of millions of dollars each year.
This interactive map from Esri tells the story of the spotted laternfly’s arrival and spread across the US. With a mix of animations, illustrations, and narrative, the map documents where lanternflies exist now and where they might go next.
When you open the map, you’ll notice a spotted laternfly walking across it. It’s a subtle technique that immediately draws you into the story and frames these bugs as unwelcome visitors.
As you continue, the map shows the spotted laternfly’s arrival from China in 2014 and where it currently exists in the US. Data from New York State Integrated Pest Management shows the spotted lanternfly now spans 14 states, from Iowa to New Hampshire.
The view of laternfly suitability is even more alarming. Based on analyses from the United States Department of Agriculture (USDA), this view reveals that nearly every contiguous state in the US could be home to lanternflies. Only North Dakota is spared.
Lanternflies feast on a wide variety of plants, such as grapes and willow. They also secrete a substance that attracts fungus on the plants they’ve fed on. They pose an existential threat to economies centered around agriculture and natural resources.
But it’s not all bad news. The map highlights how governments have responded as well as lessons learned from battles with other invasive species. It also includes concrete steps people can take to reduce the spread of invasive species. And the map itself becomes a tool in the fight. Through engaging design and a focused narrative, it tells a compelling story about why people should care and where to be vigilant.
