When a waterlily beetle (Galerucella nymphaeae) vanishes from the surface of a pond, it hasn’t just disappeared; it’s gone water-skiing at high speed – 0.5m/s, equivalent to a human traveling at around 500km/h. Flying along the surface on four legs, the beetles also generate ripples in the water as they bounce along the top of the water.
