From: Scheimpflug lidar range profiling of bee activity patterns and spatial distributions
Modulation power frequency distributions. Green curve represents the wild insects observed in rw region, red curve represents the hive activity in the rh region. The purple curve represents the foraging bees observed in the rfo region. Median intensity is plotted as a solid line and the IQR between 25 and 75% as a band. The insect observations recorded in the rh and rfo regions are assumed to be honeybees in the model. This is supported by the spectra, since they show a strong peak between 180 and 220 Hz
