what the heck is this nasty thing?

I found this little nasty on my parents' patio this morning. It screams at you if you do anything to disturb its equanimity, such as, say, stare at it too long in a fashion it determines to be menacing.

Needless to say, we did not test its patience too long. But we did try looking it up in our bug almanac. We think it's a Madagascar beetle, otherwise known as the Madagascar hissing beetle.

Screaming...hissing....whatever. He's an ill-tempered little guy.

Ugly, too.
