> The magic of animal electrostatics is all about size. Large animals don’t meaningfully experience nature’s static—we’re too big to feel it. “As humans, we are living mostly in a gravitational or fluid-dynamics world,” Ortega-Jiménez said. But for tiny beings, gravity is an afterthought. Insects can feel air’s viscosity. While the same laws of physics reign over Earth’s smallest and largest species, the balance of forces shifts with size.

Very cool article. For example: butterflies accumulate a positive charge when beating their wings, which causes pollen to jump through the air toward them when they land on flowers.
