Research questions old bee assumptions

Research from the University of Freiburg, Germany, appears to show that bees follow individual flight paths when foraging.

My summary: The waggle dance is imprecise ("there's nectar about X distance away at this approximate bearing") but when an individual bee has found a nectar source it can navigate very accurately to-and-from the source.

Here's one of the diagrams from the paper. 

On the left, the purple lines are next to the green lines. In the middle, the four sets of green lines are labelled blue,
green, orange and yellow. Are you paying attention? Some of the flights are from the hive (outbound) and some of the
flights are to the hive (inbound), which is a relief for all concerned.
