  In windy conditions, the air is turbulent. The strong and intermittent
velocity variations of turbulence are invisible to flying animals.
Nevertheless, flying animals, not much larger than the smallest scales of
turbulence, manage to maneuver these highly fluctuating conditions quite well.
Here we quantify honeybee flight with time-resolved three-dimensional tracking
in calm conditions and controlled turbulent winds. We find that honeybee mean
speed and acceleration are only weakly correlated with the strength of
turbulence. In flight, honeybees accelerate slowly and decelerate rapidly,
i.e., they break suddenly during turns and then accelerate again. While this
behavior is observed in both calm and turbulent conditions, it is increasingly
dominant under turbulent conditions where short straight trajectories are
broken by turns and increased maneuvering. This flight-crash behavior is
reminiscent of turbulence itself. Our observations may help the development of
flight strategies for miniature flying robotics under turbulent conditions.
