You may have noticed New Jerseyans doing a strange “dance” before the weather turned cold. It’s the Spotted Lanternfly Stomp, and it was performed in a variety of outdoor settings, including sidewalks, public parks, private yards, farms and orchards.

The purpose of the Stomp was to help eradicate the spotted lanternfly, an invasive insect that can suck the life out of plants and trees, including valuable agricultural crops.
