Most species of wild bees are in decline in Europe, according to an analysis covering the last century
A study led by the CSIC, which has analysed more than four million records of wild bees and hoverflies — known as flower flies — in Europe over the last century, shows that the majority of bee species and approximately half of the hoverfly species have experienced a decline. The study, published in PNAS, covers data on 88 per cent of these species and highlights that, by region, there were declines in the Atlantic and continental zones for both groups of pollinators, whilst recent increases were observed in the Alpine region in the case of bees.
