10. What is robbing? Describe a robber bee.
Robbing among bees is about the same thing that it is among people. A bee that invades another hive is a robber bee. If the hive is unable to defend against the robber, the robber will gather as much honey as it can carry and take it back to its own hive. This is done during times of low nectar availability (it's a lot less risky for a bee to gather nectar than it is for her to invade another hive).
