For the record I think they are more individuals than people often credit. It doesn’t seem that way when things are going well, but have a colony start falling apart and you can see they’re still separate insects managing as well as they can.
But they’re also not really strangers. They’re almost always families, and recognize one another as such by scent. They are exceptional at how, but that animals will spend their lives working to help family is of course not that unusual on its own. Humans are I think still our own special case.
