If I was a bug

 

I would be a larva so I could use my larva powers for the good of the colony.  And because all they do is wiggle around.  And I would be able to morph in to stuff.  Like a mosquito and give people west nile and buzz in there ear until they go insane.  Also larva are usually in a big group of other larva so we can have an army of insects to take over the world.  And I would get to live a really long time.
