Table 1. An overview of the datasets collected in order to identify compounds in nectar and queen’s presence.

“Scenario “N recordings” denotes the number of individuals with buzzing sounds recorded; “Total duration” represents the total recording time in each case; N colonies denotes the number of colonies in which we recorded sounds; N frames represent the colony size.
