Ladybirds native to the UK and other European countries are declining fast as the invasive harlequin species spreads, scientists have shown.

Researchers found that seven out of the eight native British species they studied have declined, with issues also identified in Belgium and Switzerland.

The harlequin is an Asian species brought in for pest control, but which has now become a pest itself.
