A whirligig beetle is a small, typically black beetle known for its habit of swimming rapidly in circles on the surface of the water 🌀. They belong to the family Gyrinidae. These beetles have unique divided eyes, allowing them to see both above and below the water at the same time. They often gather in groups, creating a swirling, mesmerizing effect. They feed on small insects and other organisms on the water's surface. Imagine them as water skaters doing acrobatics.
