Unfortunately no. It was probably about a year ago and searching around for "ants" videos isn't coming up with anything. I've noticed that after a while YouTube will remove the red border to indicate you've watched a video.

I can say for sure it wasn't a Kurzgesagt video, but they have a number of videos about ants. I haven't seen all of them but their videos are usually high quality: https://www.youtube.com/results?search_query=Kurzgesagt+ants

The video I'm thinking about had pretty big black "warrior" ants scout out an area and engage with termites, I'm not sure of their species. Based on my memory it felt like a documentary style video. It was all live captured video with a narrator, not an animation.

To be honest I'm not super into ants. It was one of those videos that somehow landed in my feed and I was pleasantly surprised because I like learning about new things.
