Many of Britain’s native species of ladybirds are suffering serious declines in numbers, thanks to the arrival of the harlequin ladybird.

It has been declared the UK’s fastest invading species, after reaching almost every corner of the country in just a decade.

It preys on native ladybirds and is believed to have caused the decline of at least seven species, including the popular two-spot ladybird, which – when last assessed in 2012 – had slumped by 44% in numbers.

A new ladybird has arrived in Britain. But not just any ladybird: this is the harlequin ladybird, Harmonia axyridis, the most invasive ladybird on Earth.


The harlequin ladybird was introduced to North America in 1988, where it is now the most widespread ladybird species on the continent.


It has already invaded much of northwestern Europe, and arrived in Britain in summer 2004.
