Millions of painted lady butterflies seen across UK in once-in-a-decade phenomenon

Things are on a knife edge in the ashes, the roads are very busy at the weekend, the butterflies are back in numbers – it must be summer!

Millions of painted lady butterflies are bringing colour to the UK in what has been described as a once-in-a-decade migration.

Hundreds of sightings of the insect – which generally live in North Africa and the Mediterranean – are being recorded across the country every day.

Although thousands fly here every summer, the current warm weather, plentiful food supplies and good wind conditions as they fly north have all meant a bumper arrival this time round.
