== Questions and a comment == 

 This is article is fairly well-written and quite interesting. I have a few questions and a comment. 

 1. How do queens get killed by worker bees? 

 2. How do two queens fight to death? 

 3. "Honey bees use special pheromones, or chemical communication, for almost all behaviors of life" Should it be "chemical communicators"? 

 4. "Honey bees are an excellent animal to study with regard to behavior because they are abundant and familiar to most people. An animal that is disregarded every day has very specific behaviors that go unnoticed by the normal person". These sentences are strange. I would remove them (let me know what you think).
