The European Ladybird Survey aims to encourage the recording of ladybirds across Europe. The app enables people to contribute more easily to the UK Ladybird Survey whose results have already shown declines in native species such as the 2-spot ladybird in response to the arrival of the harlequin ladybird, first recorded in England in 2003. Over the coming years we hope to extend the app and associated website to include all European countries. We are excited to have the opportunity to collaborate with you all in mapping the distribution of ladybirds at this large scale. Over time the information gathered will be used in many different ways to assess the status and trends of European ladybirds.
