Abstract
Fire ants are a notorious invasive insect found all over the world. Like flocks of birds and schools of fish, fire ants can be found in large aggregations. Here, we show that fire ants avoid each other on the water surface. As a result, small rafts quickly separate. To aggregate together in larger numbers, they rely on surface tension forces, the same ones that bring Cheerios together in a bowl of milk, to overcome their exploratory instincts.
