While in my sister's driveway in the middle of suburban Michigan last week, we happened across this very impressive praying mantis, who could give this guy a run for his money.
I took the risk of being devoured just to give you an idea of how big this guy really was.
Click on the first image to enlarge it. It always amazes me to see close-ups of insect faces; they have so much personality. Praying mantises appear to have rather pleasant personalities; kind of like your favorite science teacher, or Mahatma Gandhi. However, we know that appearances are deceiving, because I have personally witnessed a praying mantis devouring a live cricket in a most un-Gandhi-like manner.
