windshield rider

The other day when I got into my car I noticed a brown leaf under the windshield wiper. As I drove the leaf began crawling up the glass–turned out it wasn’t a leaf. Anyone know what kind of insect this is?

UPDATE: Thanks to everyone who emailed/commented/etc. to inform me that my traveling companion was a mantis, AKA praying mantis, of which there are over 2,000 different species.
