What have they done to the ... and where our bees are right now

Our bees seem to like the small flowers of wild wine. Near our house there is a large metal fence around a plant, full of it. That's where our girls are right now, together with lots of bumble bees.

Talking about flowers; Jürgen Tautz explains in his book about bees: The buzz about bees that nature generally is arranged in a way that there is a sense in everything and that energy should not be wasted. That explains why a bee during one day always flies to the same kind of flower. So no pollen is wasted and they themselves have less work in transforming it. Every pollen has to be transformed in a different kind of way. If they always changed the type of flower they would have to change the proceedings every time and that wouldn't be very effective.

Not very good to see on the picture: the different honeycombs store the different colors of pollen, there are yellow, orange and blue ones.
