Bumblebees seem to have feelings once they are awarded with something they please. Many people (preferably scientists) have tried to prove or disprove this theory, by awarding them and testing their emotions. They've used different color flowers and sugar/honey goods for the bees to either signify or interact with. Many bees had been given tasks, and were guided to do certain things, and once these tasks had been accomplished, they were motivated to do more so by being given sugar.
