'Swarm of flying ants' confuses weather radar in England

Clouds of flying ants in southeastern England have fooled weather forecasting radar into showing rain over the area.

"It's not raining in London, Kent or Sussex but our radar says otherwise," the Met Office, Britain's official weather forecaster, tweeted.

"The radar is actually picking up a swarm of #flyingants across the south-east," it said.

It explained "ants can take to the skies in a mass emergence usually on warm, humid and windless days".

The flying ants are known as alates and are normally sexually mature queens and male black garden ants, according to Britain's Natural History Museum.

The ants swarm to find mates after which the queens chew off their wings and lay eggs in new colonies, the museum said.
