The number of bee species has been decreasing for decades and, in Britain, the insects have been lost from a quarter of the places where they used to be found 40 years ago.
How intelligent are bees?
Bees are highly intelligent creatures. They can count, solve puzzles and even use simple tools.
In one experiment, bees were trained to fly past three equally spaced, identical landmarks to reach a sugary reward that was placed 300m away. When the number of
