Mouse Actions

Hi there
I have a movie clip of a butterfly. I would like to create some mouse actions controlled by the user where when they "mouse over" the clip, the butterfly moves away from the mouse - almost like the mouse scared the butterfly away.

Then the mouse will land in a different spot... There are about 3 or 4 spots the butterfly will land within the main movie and again, if the mouse "scares" it, it will move to another of those 3-4 spots.

Any idea on a tutorial or do you have a way I can get started with this clip?

Thanks!
