The Geranium macrorrhizum are trying to escape. They are squeezing through the railings and cascading over the wall!
The bumblebees still managed to catch them though. When bees fly they build up a positive electrostatic charge, whereas flowers have a negative one. When a bee approaches a flower the difference in the charges causes a spark in the electrostatic field. New research shows that this electrostatic energy causes the bee’s hairs to move. These vibrations from the hairs are picked up by the bee’s nervous system and the bee can then interpret these signals.
As you can see, bees and flowers are in such harmony. As the bee feeds, so its fluffy bum is picking up a load of pollen, ready to be dabbed onto the next flower. And now we know that they “chat”!I think this might be a garden bumblebee, Bombus hortorum. I was confused by the lack of a second yellow band on the thorax (which is very shiny), but then I read here that they are prone to baldness! If so then apparently they have the longest tongue of any UK bumblebee, up to 2cm, enabling them to reach the parts of flowers other bees cannot reach.
