Yeah, there's even a scientific term for the difference. "Eusociality" referring to animals that live in colonies where each individual has one of several (morphological different) roles. It includes several types of insects (bees, wasps, ants, termites), as well as some more basal lifeforms like hydrozoa. The only eusocial mammal (and only vertebrate as well, I believe) is the Naked Mole rat.
