What metaphors are used in Protagoras and Meno by Plato?

From the text:

"I wanted one virtue and I find that you have a whole swarm of virtues to offer. But
seriously, to carry on this metaphor of the swarm, suppose I asked you what a bee is, what is its essential nature, and you replied that bees were of many different kinds. What would you say if I went on to ask, And is it in being bees that they are many and various and different from one another? Or would you agree that it is not in this respect that they differ, but in something else, some other quality like size, or beauty?"
