Corpse-eating flies thought to be extinct are back, and hungry

Behold the bone-skipper, high in the running for the strangest fly on Earth. For the bone-skipper, fresh carcasses just won't do. No, these flies prefer large, dead bodies in advanced stages of decay. And unlike most flies, they are active in early winter, from November to January, usually after dark.

They also disappeared from human notice and were declared extinct for more than a century. That's why they've often been considered almost mythical or legendary, said Pierfilippo Cerretti, a researcher at the Sapienza University of Rome.
