a Insect activity over time, range and flight height. Each dot represents one observation. Observations recorded in the lower transect are plotted in blue. Observations from the higher transect are plotted in orange. The majority of observations are recorded close to the beehive at 180 m. Note that the variation in ground level is exaggerated by the different scales on the height and distance axes. b Distribution over range during the third day for both transects. In the lower transect, we see a high number of bees concentrated in a small area, whereas in the higher transect, we see fewer and a broader distribution of insects which indicates a “funnel like” distribution above the beehives. c Median frequency composition and IQR for the low and high transect within 15 m of the beehives. Insect in the high transect have a 7% higher average wingbeat frequency. The lower transect also shows more activity at lower frequencies from wild insects
