A study by the World Wide Fund for Nature (WWF) found that many species of bees are on the brink of extinction in parts of the UK, while some species have completely disappeared.
Analysis of 228 species of bees concluded that climate change, habitat loss, pollution and disease threaten pollinators.
The World Bee Day report found that 17 species of bees were extinct at the regional level – including the Great Yellow Bee, the Flower and Cliff Mason bee – with 25 endangered species and 31 other species those need to be preserved so as not to become extinct.
The value of pollination services for the bees cost the British economy 690 million pounds annually, the World Wide Fund for Nature study said.
