RE: Some species of ants and termites perform suicidal altruism where they explode to protect the rest of the colony from an intruder

I would probably not go as far as calling it common though. I don't think we will ever find this behavior outside of eusocial organisms, and it's still rare within this group as well. But who knows? We might end up finding more species who does this in the future.
