Honey bees (Apis mellifera) in house-hunting swarms perform vibration signa
ls (dorsoventral abdominal vibration (DVAV)) of 18.05 +/- 0.45 Hz for 1.36
+/- 0.23 s throughout the house selection process. These signals are perfor
med by a specialized subset of bees, most of whom never perform recruitment
dances to nest sites. Individuals repeatedly vibrate others. The patterns
of vibration signal performance are consistent with the hypothesis that it
serves to activate bees for take-off, but may also activate bees to scout f
or nest sites.
