CBS NEWS - A fight is ramping up against the New World screwworm fly as it spreads to the United States, and, in what sounds like science fiction, it lays eggs that hatch into flesh-eating parasites.
So far, the fly has not been detected in California, but scientists are on the lookout.
Entomologist Amy Murillo shared a rare, up-close look at the flesh-eating fly now terrorizing cattle and dairy farmers.
"The spines here are just like truly amazing," she marveled while viewing the larva under the microscope.
