Bee-Like Mob

I would like to create a bee-like mob called the Casbee, but how to do the spawning in a hive. I am going to add the aggression part and when it gets attacked it will buzz around in a circle along X axis. I also want to make a manmade beehive and custom flowers that only can exist in the custom dimension the Casbee is in for it to pollinate. How to make the aggression so that it will notify any Casbees around to fight you or any mob which dares to savour the sweet Casbee Jelly. If the Casbee army is lacking, it will summon a queen and it will be powerful. It is a miniboss that summons an army of Casbees to deal with you and it will drop more Casbee Jelly than a normal Casbee. They are a force to be reckoned with... So, please help me on the notification of other Casbees to turn hostile and attack, beehives and the spawning.
