<human>:  Are aggressive bumblebees suicidal?
<bot>: No, bumblebees are not suicidal. They are aggressive. Bees with barbed stingers lose the barb after attacking a victim and die soon afterwards. Bumblebees do not have barbed stingers and can sting multiple times without dying. So, bumblebees are not suicidal. They are aggressive, not suicidal.
