"Non-native species that become invasive are one of the greatest threats to wildlife worldwide. They are estimated to cost the British economy at least £3billion a year, and their impacts can be far reaching - they have adverse impacts on our native wildlife by predation, competition and spread of disease. They can threaten economic interests such as agriculture, forestry, fisheries and development."

"People's enthusiasm for recording wildlife is inspirational. Over the last five years thousands of people across Britain have contributed records to the Harlequin Ladybird Survey, providing valuable insights into the ecology of this invasive species, its spread throughout the country, and its impact on native wildlife. I am sure that the new surveys launched today, within the Recording Invasive Species Counts project, will be just as successful."

"It is important that awareness of non-native species is raised and their effects better understood. By providing records, members of the public can play a vital role in helping scientists track non-native species and better understand their ecology."

"The Harlequin Ladybird survey highlights the enormous potential for engaging the public in helping us manage non-native species. I look forward to seeing the results of this project and urge everyone to get involved in spotting these species and making a report."
