  It has been repeatedly reported that the collective dynamics of social
insects exhibit universal emergent properties similar to other complex systems.
In this note, we study a previously published data set in which the positions
of thousands of honeybees in a hive are individually tracked over multiple
days. The results show that the hive dynamics exhibit long-range spatial and
temporal correlations in the occupancy density fluctuations, despite the
characteristic short-range bees' mutual interactions. The variations in the
occupancy unveil a non-monotonic function between density and bees' flow,
reminiscent of the car traffic dynamic near a jamming transition at which the
system performance is optimized to achieve the highest possible throughput.
Overall, these results suggest that the beehive collective dynamics are
self-adjusted towards a point near its optimal density.
