Q When The Rock‘s Stanley Goodspeed (Nicolas Cage) enters a safety chamber in FBI headquarters to defuse a gas bomb, he carries in a glass case of live roaches. When the poison mist is released, the roaches start thrashing and dying and erupt in a mass of red blood. Do roaches really bleed red?

A As any New York City apartment dweller will testify, roaches do squirt when you squish them. But as entomologist Louis Sorkin of the American Museum of Natural History notes, ”It’s not the same style of blood as mammals’. It’s straw-colored.” Sorkin also doubts there would be as much blood as the movie showed, but he volunteered to squash some museum lab roaches just to be sure. ”There’s usually a lot of a white fatty substance and a little blood.”
