A third of British wild bees and hoverflies are in decline, according to a new study published in the journal Nature Communications.
If current trends continue, some species will be lost from Britain altogether, the scientists say.
The study found “winners” and “losers” among hundreds of wild bees and hoverflies, which pollinate food crops and other plants.
Common species are winning out at the expense of rarer ones, with an overall picture of biodiversity being lost.
Scientists warn that the loss of nature could create problems in years to come, including the ability to grow food crops.
