U-turns... I am not sure if there is any data from LIDAR, tagged bee, or other bee-tracking studies that would help here, but I've not seen any mention of bees flying downwind and then turning into the wind when navigating to forage.
But there has been no mention of such unusual behavior in the data gathered from such studies, and it would be significant to our understanding of how bees forage / navigate / view the world.
I do know that bees heading back to the hive follow the an oft-mentioned "bee line", once they are above the tree canopy or other terrain feature, such as a building. They consistently follow headings that are accurate enough to allow triangulation of the paths followed by multiple bees released from point A, and then multiple bees released from point B, if A and B are several hundred yards apart, regardless of wind direction.
If they consistently flew first downwind, and then upwind along an "odor plume", I think those of us who bee-line would have noticed it, even if no one else did.
