Beetles changing their identitiy

As I was watching the news the other night I heard a quick blurb about these certain types of beetles that can change their identity.  Meaning that they make themselves smell like bees.  They are too small to get where they need to go so when they change their scent and the male bees come-a-lookin the beetles hop on and when they get to their destination, via the bee, they hop off.  I laughed at this at first then thought although deceiving it was a great way to get what they needed.  I then started to think more about why humans may change their identities.  The obvious ones, running from the law, running from a very abusive relationship.  Then I started thinking about the discussion we had in class about the online game Muds and how some people will use that site to be someone else.  Anyways thanks to the beetles it just got me thinkin.
