Huge swarms of flying ants in the south of England have appeared on a weather forecast map looking like rain. Large numbers of what the Met Office described as "insect clutter" were recorded on radar systems between 8:00 and 11:00 BST. Weather presenter Simon King said: "We knew it was dry in the south of England, and yet the radar was showing this very light precipitation across the south. You can tell it's not rainfall because it has that eerie look to it. It doesn't quite match what rainfall looks like."
