Ladybird 'risk to 1,000 species'

The insects are the fastest-spreading alien species on record The Harlequin ladybird is putting over 1,000 species in the UK in peril, scientists have warned. "The rate of spread is dramatic and unprecedented," said Dr Helen Roy of the Centre for Ecology and Hydrology. The ladybird has spread to most parts of the UK in just four years, preying on many other insects. However, research outlined at the Royal Society's Summer Science Exhibition suggests local ladybird parasites are adapting to prey on the interloper. To help that process along, scientists are suggesting introducing a mite that renders the ladybirds infertile. MORE
