That's a gorgeouse pic of a praying mantis, they're among the coolest insects I've seen. Leave it there, it hunts other insects and hopefully will keep pests down.
A little more trivia, the female eats the male alive while they're copulating (extra food reserves for their offspring)... I'm so glad I'm not a male mantis! /ubbthreads/images/graemlins/eek.gif
