So many ants are flying across England that they are being picked up on radar, the Met Office had revealed.
Meteorologists were baffled when sensors in the South East picked up what seemed to be rain, but people in London, Kent and Sussex were enjoying a dry and cloudless day.
Examining the shape of the 'droplets', which were picked up by radar, they found that they appeared to be insect-shaped.
They then investigated on social media, to see if anyone in the local area was posting about an insect swam, and found that hundreds of people were complaining about hordes of flying ants.
In mid-July, ants grow wings and fly high in the air, swarming together in the sky to mate. This causes a nuisance for those trying to enjoy a fine day outside, as they are prone to gathering in the sky and landing in drinks and on books and surfaces. They are often spotted by sunbathers as they prefer to mute in hot, dry and humid weather. This annual phenomenon is referred to as 'flying ant day'.
