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.

The distribution map on the left or the annnual spread maps show that it has spread rapidly north and west from the southeast of England since its first sighting.

There are 46 species of ladybird (Coccinellidae) resident in Britain and the recent arrival of the harlequin ladybird has the potential to jeopardise many of these. The Harlequin Ladybird Survey will monitor its spread across Britain and assess its impact on native ladybirds.

Monitoring ladybirds across the country has never been more important. We want YOU to get involved! Please record your harlequin ladybird sightings
