Not calm, but definitely very controlled. However, chimpanzees and related primates prefer to steal honey from stingless bees like Meliponula bocandei.

This may include alarm pheromones as a component, but even if it doesn't I suspect bees can easily detect the presence or absence of human sweat. The article The Chemical Compositions of Insect Venoms says it so well I will just quote them, “Sadly, this is something of an over-simplification. Well … perhaps not. As I have discussed elsewhere, there are certain times during the season when colonies can become defensive. Your email address will not be published. Less than a big brown bear.
