The video was shared in a post titled "While out on a walk I came across these ants. What is going on?" uploaded on August 18 by Linnea, a 30-year-old dog groomer in Monticello, Minnesota, under the username u/Latter_Composer_2235. The clip has amassed 18,000 upvotes and thousands of comments in the r/whatisit subreddit.

"I live in Minnesota and I've never seen anything like it," Linnea wrote in the caption. "There were two 'piles' and they were all just writhing around."

Linnea, who did not shared her last name, told Newsweek : "I had not personally seen anything like it before. The consensus on Reddit was that they were having a battle for territory."
