How are Whirligig Beetles (Gyrinidae) recognized by their movement?

Answer

Skating in circles on the water surface

The Whirligig Beetles, or Gyrinidae, are instantly recognizable due to their unique behavior centered on the water surface. They utilize specialized, paddle-like short legs to propel themselves, skating rapidly across the surface film in intricate, swirling, circular patterns. This behavior is linked to their feeding strategy, as they are surface feeders and predators, constantly monitoring both above and below the water for prey or threats using their uniquely adapted eyes.
