What's going on with these mantises? Are they about to fight? Are they posing for a picture? Are they even alive? Yes, they are alive, but it appears to be a kind of stand-off, where they are bluffing each other, waiting and even daring one of them to make the first move.
Turns out they are in their fighting stance in reaction to the camera. They sure are pretty, for a bunch of bugs. Adrian Kozakiewicz of InsecthausTV has plenty more videos that delve into the mysterious world of insect behavior. (via Boing Boing)
