They seemed to only be contained within the map that they spawned in at the moment (i.e. the maps with that blue symbol smacked on it).

That said, its been explained already that in order for them to spawn on a map, you have to repeatedly complete that map, and when you get a black screen after a map with blue lightning, it means that they are going to start spawining in that map from now on.
