Visiting alien creature

This odd-looking fella decided to hang out in our bathroom yesterday. He's Microcentrum retinerve, commonly called a katydid. The common name refers to the sound they make, using file-like organs on their hind legs to scrape against their wings. This sound-making method is called "stridulation."

They also do a great job of impersonating a leaf - which is useful, unless you hang out in someone's bathroom.
