Records for the UK Ladybird Survey, consisting of surveys for the harlequin ladybird, data from the London Natural History Society (collated by Paul Mabbott), and the UK Ladybird Survey. Data have been collated by the Biological Records Centre. Many people have provided data to both the Harlequin and the UK Ladybird Survey through the on-line surveys. The data from both on-line surveys (www.ladybird-survey.org and www.harlequin-survey.org) are collated within this dataset. Many county recorders, natural history societies and other wildlife groups have contributed to the survey, with the help of Paul Mabbott (London Natural History Society), Nigel Cuming and Jerry Bowdrey (Essex Field Club/Colchester Museum) and Michael Majerus. Many entomologists have provided survey data and this information is available in the Survey section.
