In what could be the biggest influx of butterflies into this country in decades, millions of Painted Lady butterflies have flown into Britain from the deserts of north Africa.

Painted ladies reach our shores every summer, but the last major migration was in 1996. This year, rumours of an impending invasion began circulating in late winter. A Spanish scientist, Constanti Stefanescu, reported seeing hundreds of thousands of them emerging in Morocco in mid-February after heavy winter rains in north Africa triggered the germination of food plants devoured by its caterpillars. Aided by favourable winds and unimaginable reserves of stamina, large numbers were seen in Spain during April. A few weeks later, they had reached France.

On the coast, all you may see is a flash of orange whizz past at head height. When they settle on garden flowers they are as striking as their less adventurous relatives, the red admiral and the small tortoiseshell. Certain weeds should be very afraid: painted lady caterpillars feast on thistles before emerging as an immaculate new generation of adult butterflies in August.
