What is the type of bee that lives in Africa (southern i think) that infiltrates other bees hives and lays eggs there. The other bees in the hive think that these eggs are theirs, thus taking care of them.. in the end the hive goes into utter chaos and the queen bee ends up dying.

Anyways, I thought they were called "bully bees" but can't seem to find anything about them on the net. Any information would be deeply appreciated.
