The queen approaches you first and asks for your help, then the mage/wasp approaches. While talking to the wasp he explains that he needs to help the wasps so that their queen will transform him back to his original state, then he will say "...the wasps are the stronger race so they should rule here." You can reply
"1. I agree. the wasps have the right to be here. I will help you against the bees so that you may also regain your natural form."
in which case you will help the wasps and kill the bees, or
"2. You are wrong. The bees have been here for a long time. It is their home. Your waspish interlopers cannot be allowed to force them to leave."
and help the bees / kill the wasps.
There is a third choice to tell him you might help, but the queen bee has a key you need. He will lie and say he has it, and you will get two choices again, to be on his side or support the bees.
