Derek Mooney finds out how the harlequin ladybird became the UK's fastest invader ever.

Derek Mooney investigates with ladybird expert Dr Helen Roy, how a little beetle became the world’s fastest invader. From 2016.

In years since the harlequin ladybird first hopped across the English Channel, its spread has been scrutinised by an army of scientists and amateur naturalists.

Its rapid colonisation has given it the unfortunate title of the world's fastest invader. Derek Mooney talks to ladybird expert Dr Helen Roy to find out how this little beetle came to be a great invader.

Telling the stories of non-native invasive species and our complicated attitudes to them and with an uncertain political future, how do we police our ecological borders?
