[Alien] What happens to elderly xenomorphs?

So let's assume this specific xenomorph is strong and smart enough to survive for a prolonged amount of time, there is already a queen in the hive so there's no use for them to grow into one, what would happen?

The strongest and smartest ones are turned into Praetorians by the Queen. Those would be the ones who survived that long. They protect the queen, act as generals and can replace the queen if she is killed.
