A new report is warning that over the last decade native ladybird numbers in the East have been virtually wiped out.

Climate changes and farming practices are having a slight impact, but the biggest problem is attack from an invasive ladybird called the Harlequin.

The research, published in the journal Insect Conservation and Diversity, involved taking recordings at four sites across East Anglia, nine times a year over an 11-year period from 2006-2016.

Native ladybirds recorded across these sites have declined from 99.8% in 2006 to just 30% in 2016. Only one solitary harlequin ladybird was recorded as part of this study in 2006. Now they account for up to 70% of the ladybirds.
