The first clip shows the Brazilian stingless bee Scaptotrigona aff. depilis driving away four Melipona quadrifasciata foragers by lunging at and biting them. The second clip shows more intense aggression, as a Trigona hyalinata forager flings a M. quadrifasciata forager off the artificial flowers. These artificial flowers provide sugar water to the bees.
