An invasion of Asian ladybirds that could wipe out our native species has been going on for months, researchers have found out.
The alarm was raised last month after a single foreign harlequin ladybird was discovered in an Essex garden.
Bug expert Dr Majeras asked people to send him any suspicious looking bugs and since then many more have been discovered around the country.
He believes that it could now be too late to stop the invaders.
The harlequins have been found in London, Folkestone, Ipswich, Newmarket and Canterbury, some were at least two or three months old.
