A newly discovered wasp has been keeping a gruesome secret: It stuffs ant corpses into the walls of its home.
As far as scientists know, the behavior is unique in the animal kingdom. The new creature has been named Deuteragenia ossarium, or the "bone-house wasp," after the historical ossuaries piled high with human skeletons found in monasteries or graveyards.
