Anglia Ruskin scientist launches book at BBC Gardeners’ World Live event
The first atlas of Britain and Ireland’s ladybirds, which is the result of a six-year research project by the UK Ladybird Survey, is being launched today [Wednesday 15 June].
The new publication maps all 47 species of ladybirds in Britain and Ireland, building on thousands of observations from volunteers. The earliest record in the atlas is that of the rare 13-spot ladybird, recorded near Oxford in 1819. The most commonly recorded species, with 27,000 records, is the 7-spot ladybird, closely followed by the newly-arrived harlequin ladybird with over 25,000 records.
‘Ladybirds (Coccinellidae) of Britain and Ireland’ has been written by Dr Peter Brown from Anglia Ruskin University, Dr Helen Roy from the Centre for Ecology & Hydrology, Dr Remy Poland from Clifton College and wildlife enthusiast and ladybird recorder Robert Frost.
Dr Brown, from the Department of Life Sciences at Anglia Ruskin, said:
Within ‘Ladybirds (Coccinellidae) of Britain and Ireland’ there is a detailed analysis of ladybird observations from the last 20 years. The results show that 10 ladybird species have significantly declined in this period, whilst five have increased. Distribution maps are provided for each species together with information about recording techniques, species identification, ladybird parasites, historical aspects, and 194 colour photographs.
Declining species include the 14-spot and 10-spot ladybirds, which are principally greenfly (aphid) feeding ladybirds coveted by gardeners. Species doing well, and expanding their geographical range, include the pine ladybird and the mildew-feeding orange ladybird. Previously the orange ladybird was a rare species but it has thrived in recent years, partly by adapting to life on different types of tree.
The book is being officially launched today [Wednesday] at the BBC Gardeners’ World Live exhibition in Birmingham, which is a major annual event run in association with The Royal Horticultural Society.
Following on from last year’s BBC Springwatch-linked Breathing Places activities, for which the UK Ladybird Survey was the main wildlife survey, the UKLS team have been invited by the BBC to line up alongside Monty Don, Alan Titchmarsh and other experts to help explain the importance of having ladybirds in the garden.
