The modulation of shimmering by hovering hornets regarding their distance to the honeybee nest (<i>scenario B</i>).

Shimmering activities of 201 episodes in terms of Wpeak and W600 in dependence of the pre-wave distances of the hornets from the nest (definitions, see Methods). The hornet data (dxz) were assessed in the interval 400 ms prior to shimmering. Shimmering responses (means±SEM) were categorized by five classes (Cdxz = 1 to 5) of dxz (cf. Fig. 3A).
