Tutorial Request: Butterfly AI Breakdown

Oh, those wonderful little butterflys in the new office example project, how awesome they are. Unfortunately, they have a big jumble of a blueprint full of things that I am not quite sure how they work and I am not sure how I would test/figure out how to use without recreating the entire butterfly blueprint. So, I was wondering if anyone would be able to breakdown the separate components of the butterfly AI blueprint into standalone chunks that could be toyed with in order to get a feel for how they work on their own. A video tutorial/walkthrough of the process would be appreciated as well (not that I’m not asking a whole lot already :D).
