If you’ve been out and about this week, especially in southern parts of the UK you may have encountered swarms of flying ants.

Flying Ant Day, which typically falls in mid-July, when queens and males take flight to start new colonies, although it can take place over several days.

On Friday, the Met Office spotted a mile-long cloud of winged insects on radar, often mistaken for rain.

Although annoying, the ants are not dangerous and tend to emerge during warm, calm weather.
